WebDAV How, What and Problems…
What is WebDAV?
WebDAV stands for "Web-based Distributed Authoring and Versioning".
It's a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers.
It can also be used to access mail on exchange server. I used it for this.
It great for accessing Exchange because all you need is an XML body sent over HTTP. No installing of anything.
How it works?
WebDAV works with XML. It sends xml requests to the server and gets the responses in return.
It uses MSXML or System.Net.HttpWebRequest in .NET.
WebDAV has some extended keywords besides the standard HTTP ones that do it's bidding :)
Which they are and how are they formed and used can be found on this MSDN site
so i won't go into that.
The type of Request we're making (PROPPATCH, MOVE, PROPFIND, …) is specified in the HttpWebRequest's Method Property XML PROPPATCH request is created like this:
<?xml version=\"1.0\"?> <a:propertyupdate xmlns:a=\"DAV:\" xmlns:n0=\"http://schemas.microsoft.com/exchange/\" xmlns:n1=\"http://schemas.microsoft.com/mapi/proptag/\" xmlns:n2=\"urn:schemas:httpmail:\" xmlns:n3=\"urn:schemas:mailheader:\"> <a:set> <a:prop> <n0:outlookmessageclass>IPM.Note</n0:outlookmessageclass> <n1:0x1000001E>Test Text</n1:0x1000001E> <a:contentclass>urn:content-classes:message</a:contentclass> <n2:subject>Test Subject</n2:subject> <n3:to>valid@emailAddress.com</n3:to> <n3:x-mailer>some mailer</n3:x-mailer> </a:prop> </a:set> </a:propertyupdate>
Server response is like this:
<?xml version=\"1.0\"?>
<a:multistatus xmlns:a=\"DAV:\" xmlns:d=\"urn:schemas:httpmail:\" xmlns:e=\"urn:schemas:mailheader:\" xmlns:c=\"http://schemas.microsoft.com/mapi/proptag/\" xmlns:b=\"http://schemas.microsoft.com/exchange/\">
<a:response>
<a:href>http://servername/Exchange/username/Drafts/Test%20Subject.eml</a:href>
<a:status>HTTP/1.1 201 Created</a:status>
<a:propstat>
<a:status>HTTP/1.1 200 OK</a:status>
<a:prop>
<b:outlookmessageclass></b:outlookmessageclass>
<c:0x1000001E></c:0x1000001E>
<a:contentclass></a:contentclass>
<d:subject></d:subject>
<e:to></e:to>
<e:x-mailer></e:x-mailer>
</a:prop>
</a:propstat>
</a:response>
</a:multistatus>
Each Property can be saved or removed this way. Custom properties can also be added.
Exchange also has a special folder called ##DavMailSubmissionURI## to which the item must be moved to get sent.
Life of an item in WebDAV generation process and problems that arise
Here i'll explain steps that must be done to each item to get it to work properly. Request methods to use are in CAPS letters.
1. Email message
- PROPPATCH the xml request to drafts folder.
- Attach any Attachment with PUT Request
- MOVE the item from Drafts to ##DavMailSubmissionURI##
2. Appointment
- PROPPATCH the apponitment in the calendar folder
3. Meeting Requests
- Create an appointment in your calendar folder (point 2)
- COPY the Appointment in your calendar folder with a differnet URI
- set the http://schemas.microsoft.com/exchange/outlookmessageclass property to "IPM.Schedule.Meeting.Request"
- set the DAV:contentclass property to "urn:content-classes:calendarmessage"
- set the urn:schemas:calendar:method property to "REQUEST"
- PROPPATCH (save) the meeting requests properties
- Attach any Attachment with PUT Request
- MOVE the item to ##DavMailSubmissionURI##
4. Contacts, tasks and others
- PROPPATCH the request to proper folder
- Attach any Attachment with PUT Request
- MOVE the item from Drafts to ##DavMailSubmissionURI## if needed to send
Development problems and bugs
1. Property naming
A lot of http://schemas.microsoft.com/mapi/proptag/ and http://schemas.microsoft.com/mapi/id/ properties start with '0x'.
If you're using XmlDocument to store xml data like I do then you know that it doesn't allow tags to start with '0'.
Luckily replacing 0x... with x... when loading the document fixes this.
I load the XmlDocument with the xml returned from the server.
I bulid the XML request that gets sent to the server by hand. That's because http://schemas.microsoft.com/mapi/id/
properties need to start with 0x to get set properly while http://schemas.microsoft.com/mapi/proptag/ don't.
2. Case sensitivity
All properties ARE CASE SENSITIVE. all properties can be found on this MSDN site
3. Getting associated appointment from a meeting request reply
I spent a lot of time trying to figue out how to get associated appointment from a meeting request reply.
Since a meeting request is acctually based on an appointment we can deny, accept it or set it to tentative.
Now when this reply is returned to us it is basicaly a message and not an appintment.
It's DAV:contentclass is "urn:content-classes:calendarmessage" and its http://schemas.microsoft.com/exchange/outlookmessageclass
is one of the following: "IPM.Schedule.Meeting.Resp.Pos", "IPM.Schedule.Meeting.Resp.Tent" or "IPM.Schedule.Meeting.Resp.Neg"
The only property that gets preserved is:
http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/0x23
which i've named AppointmentAndMeetingRequestResponseConnector :))
This is a base64 encoded property.
4. Appointment Reccurence
I used this document: http://www.ietf.org/rfc/rfc2445.txt
paragraf "4.3.10 Recurrence Rule" and "4.8.5.4 Recurrence Rule"
This is a multivalued property so it's property must be set in the following way:
<c:rrule><r:v xmlns:r=\"xml:\">Recurrencerule Here</r:v></c:rrule>
where "c:" is a prefix for "urn:schemas:calendar:" namespace.
5. Mail body
We have urn:schemas:httpmail:htmldescription and urn:schemas:httpmail:textdescription properties
but there's no property named "Message Body" or something similar.
This property is it:
http://schemas.microsoft.com/mapi/proptag/0x1000001E
Search
Search with WebDAV is implemented with a SQL dialect. More info can be found on this MSDN site.
Never use Select * because it returns only properties defaulted to the collection and not all of the collections proerties. It's also slower since it has to go look which properties are deafult for the collection. When using search we must cast some properties to proper types.
For example when we search the calendar to get associated appointment from a meeting request reply the
http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/0x23 must be cased to "bin.base64"
XML request for this looks like this:
<?xml version=\"1.0\"?>
<a:searchrequest xmlns:a=\"DAV:\">
<a:sql>
SELECT \"DAV:contentclass\"
FROM SCOPE('SHALLOW TRAVERSAL OF \"http://servername/Exchange/username/Calendar/\")
WHERE \"http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/0x23\"
= CAST(\"BAAAAIIA4AB0xbcQGoLgCAAAAAAAAAAAAAAAAAAAAAAAAAAATQAAAHZDYWwtVWlkAQAAAENEMDAwMDAwOEI5NTExRDE4MkQ4MDBDMDRGQjE2MjVEOUI1MjY5M0U0MjVBRUU0OTkwMzcxMjE0Njk2NEZERjMA\" as \"bin.base64\")
</a:sql>
</a:searchrequest>
This requests response looks like this:
<?xml version=\"1.0\"?>
<a:multistatus xmlns:a=\"DAV:\" xmlns:d=\"urn:schemas-microsoft-com:office:office\" xmlns:c=\"xml:\" xmlns:b=\"urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/\">
<a:response>
<a:href>http://servername/Exchange/username/Calendar/Some%20Appointment.eml</a:href>
<a:propstat>
<a:status>HTTP/1.1 200 OK</a:status>
<a:prop>
<a:contentclass>urn:content-classes:appointment</a:contentclass>
</a:prop>
</a:propstat>
</a:response>
</a:multistatus>
Href property returns the associated appointment URI.
Well that's about it... :)
WebDAV is a cool protocol if you ask me and i like it.
It's very simple and powerfull to use but it's hard to find all of the little details.
You can also manipulate MS Office files with it.
Oracle and Adobe also support it and a few others like Apache, MS IIS, Subversion (open source control program)...

re: WebDAV How, What and Problems... well on the first look i think that string strAlias = "EmailAddress"; must be your username to the exchange account and not your email address. |

re: WebDAV How, What and Problems... I am Using WEBDAV to post the meeting request through my ASP.NET application. When I post the Recurrence pattern for the two months. Only one month of the organizer's calender is updated. But when the attendees accepted the meeting their calendar is updated for two months. And also In the "When: " title shows only the first occurence of the meeting only. What should be the problem? Thanks in advance. |

re: WebDAV How, What and Problems... What is your exchange server version and outlook versions of your users? Outlook 2003 has improved recurrence pattern recognition than Outlook 2000. But neither fully supports the reccurence pattern that is specified on the site in point 4. Appointment Reccurence of this artice. What is your reccurence pattern? |

re: WebDAV How, What and Problems... Ganeshgopu: i never set the rdate property. i don't know if it's even multivalued. i always set the rrule property which is multivalued but you don't really need multiple values, because every rule can be presented in a single string value. Rameshwar Sharma: Look at Search sectino of this article. SQL search is preety simple and quite powerfull. |

re: WebDAV How, What and Problems... Thanks for your response Mladen. Whats my problem with rrule is, can set different dates in any manner in a recurrence meeting. But I don't know how to set different timings for the instances. Say for example, In between 7/5/2006 to 7/15/2006, I have to request with the following timinigs. On every Saturday 05:00 am to 06:00 am On every Sunday 07:00 am to 08:00 am On every Wednesday 08:00 am to 09:00 am For the above condition how can i frame the RRULE. Assist me. Thank you. |

WebDAV 403 Error on PUT I am trying to send emails using VB with WebDAV and an Exchange Server from multiple email addresses. My problem is that the user accounts are on multiple servers, when I specify the server explicitly, sending the email works perfectly, but when I try to use the "higher-level" server I get a 403 Error on the PUT method. My code is available at http://sivic.homelinux.net:81/~kevin/SendEmails.txt Any help or ideas would be much appreciated, thank you! |
|
Mladen
2006-07-06 |
re: WebDAV How, What and Problems... "From"() is a read only property in exchange so you'll always get a 403 forbiden when trying to set it. the way to send a same mail from different accounts is to log into every account and send it from there. Sorry... i've cursed that too :)) Or did i misunderstood your problem? |

WebDAV 403 Error on PUT Mladen, thanks for your response! I believe that you misunderstood my problem though. Here is the situation, I am running a script from multiple email accounts, I get their login and password from them as input, therefore I do not have to set the From property. Then when I send the e-mail it gives me the 403 when I am using the top-level server. I am not sure exactly how the servers are set up, but I will tell you what I know and maybe you can figure it out from there. If I want to login to exchange with the web frontend I need to go to the "server1" server, just like everyone else at the company. But if I want to send email from outlook I need to set my profile to point to "server2" while others need to set their profile to "server3". So what I am trying to accomplish is to be able to send email from anyones address at the company without knowing if they use "server2" or "server3". If anyone has any ideas it would be quite helpful! TIA Kevin |

re: WebDAV How, What and Problems... wow... that's a complex setup... i guess you could create some sort of mapping file to use for server... other than that.... change the exchange server setup :)) |

re: WebDAV How, What and Problems... I have this problem of sending meeting request using webdav in c#. whenever i create a meeting request it is created fine but the start and end time are increased by twohours. i mean that if the start time is 1:00 PM it will make it 3:00 PM andsmae goes for end date. can any body help. can anybody help? |

Mladen
2006-07-27 |
re: WebDAV How, What and Problems... you probably use datetime.now? you must use datetime.UTCnow that's because all dates in exchange are stored in utc date format and they get converted to your timezone by the client (outlook, etc...) |

re: WebDAV How, What and Problems... Hi, I have put an OnSave event sink on an Exchange Sent Items folder to notify me when new Sent Items are recieved in the folder, but there is a problem with this as the OnSave Event Sink does not trigger when a new Sent Item arrives. Therefore is there anyway of the OnSave Event Sink getting triggered when new Sent Items arrive? Or do I need to use another type of Event Sink, please advise. Thank you. |

re: WebDAV How, What and Problems... I haven't worked with event sinks in exchange that much so my honest answer would be: i don't know. sorry. |

re: WebDAV How, What and Problems..."(500) Internal Server Error" Great Article.. I have question.. I am using WebDAV to update exhange calendar appointments. But when i use it to update an appointment it returns "(500) Internal Server Error" I checked the code and found that if length of HTML body of appintment in <mail:htmldescription> tag is huge then it return this error. If i reduce the size of HTML text then it works well. Any idea on size limit allowed here? and how to correct this? Any help is appreciated. Thanks in advance. |

re: WebDAV How, What and Problems... Check the inner http exception that you get in your catch block. i don't know how much is the size limit. what kind of html are you putting in theree that's so big anyway? maybe you should reconsider that. |

re: WebDAV How, What and Problems... I'm creating meeting requests using WebDAV, based on the Microsoft knowledge base article #308373 (http://support.microsoft.com/default.aspx?scid=kb;EN-US;q308373), but it must have something missing. I run the example (I changed MSXML.XMLHTTPRequest into MSXML2.XMLHTTP40), the appointment is created and the meeting request is sent. When the other user accepts the meeting from Outlook Web Access, his response is sent to me. The problem is that when I read and delete his response (now I'm using Outlook 2000), the associated appointment is deleted as well! Of course that doesn't happen if the meeting request is generated from Outlook 2000. |

re: WebDAV How, What and Problems... Items don't acctually get deleted, their just changes. So take Exchange Explorer (in the Exchange SDK) and see what properties are being set and when. Basicaly track the the meeting request. Also there are some synchronization issues with OWA and Outlook 2000. Sometimes it happened that i had to wait a few hours until they synchronized with eachother... i have no idea why though. |

Could u please elloborate more on Meeting Response. now I am using plain email response , Accepted OR Ten etc. our application is handle SMS Response. My Question is : 1. What is the exact WebDAV Format to send the Response 2. Method Propatch ?? Please send Reply As Soon As Possible Kones |

Mladen
2006-09-14 |
re: WebDAV How, What and Problems... What exactly is not clear? The person that creates an appointment sends out meeting requests to people that should attend his meeting (appointment). those invited peopele get an email to confirm their attendance. when they reply, by pressing an attending status (accept, deny, tentative) option, you get a mail for each person's reply. That is the meeting request reply. Now to get an appointment that goes with that meeting request reply you must look at the property i described in "Development problems and bugs" point 3 of this article. If that doesn't answer your question you'll have to provide me with more info. |

Mladen
2006-09-15 |
re: WebDAV How, What and Problems... You have to send the request xml i posted at the end of the article and use PROPFIND on the http://servername/Exchange/username URI. If this still doesn't work for you then post here your xml request and code. |

re: WebDAV How, What and Problems... I am trying to create and send meeting requests using webdav. I have to send meeting requests from different users mailboxes. In order to that I created a generic username/password and gave it full rights to the calendars of the intended users. My problem is that I am able to create and send them from only one of the user's mailbox, it is not working for any of the others. Everything is the same except for mailbox, and it is working for one mailbox and not for others. Any ideas what the problem might be? Is there some property that needs to be set for each mailbox or something? I would appreciate if you could reply ASAP to this. Thanks. |
|
Mladen
2006-09-15 |
re: WebDAV How, What and Problems... Is this ASAP enough? :)) there is no such proeprty to set. you have to log onto each mailbox separatly and send meeting requests. WebDav supports only operations on one mailbox at a time. |

re: WebDAV How, What and Problems... Define "Unable to set the dates". What does that mean exactly. Dates in exchange have to be set in UTC time. That's because the mail client (outlook, OWA) sets the dates according to users computer timezone. |

re: WebDAV How, What and Problems... Hmm interesting... try removing b:dt=\"dateTime.tz\" from your date properties. also look at your created task with Exchange explorer to see what properties it has set. Also set the due date property in the Outlook and see what property gets set to what value with Exchange explorer. Because your xml looks ok to me, so i can't say why i doesn't set the dates. |

2006-09-21 |
re: WebDAV How, What and Problems... Thanks for your support, but after removing b:dt=\"dateTime.tz\" this its also not set the dates, when i am looking the Task window.

re: WebDAV How, What and Problems... Hello, I'm trying to update (propose a new time) appointments that I have previously created by using the meeting request prosedure. If I do it as an organizer my appointment is updated and new meeting requests are send to recipients. After they accept the request the appointments are updated in the recipients calendar. If I try to update appointment as a recipient my appointment is updated and the organizer gets the new meeting request but when the organizer tries to accept the request comes a message that "you are the organizer you dont't have to answer the request" and the appointment is not updated. Is there any chance to get this work? How can I propose a new time for appointment using webdav? |
|
Mladen
2006-09-26 |
re: WebDAV How, What and Problems... the original organizer doesn't have to do anything with the meeting request if the time in the organizers appointment gets updated properly. if not then you have to get the appointment with the property described in "Development problems and bugs" in point 3 that connects the appointment and meeting request reply with sql search or propfind and proppatch that appointment in the organizers calendar with proper credentials. |
|
JR
2006-09-26 |

re: WebDAV How, What and Problems... Hi, I would like to retrieve attendee details of an Exchange Calendar item. Currently I can retrieve the attendee list using WebDav for attendees who have the 'Send Meeting To Attendee' option against them, but cannot retrieve the Attendee data when the 'Dont Send Meeting To This Attendee' option is selected against that particular attendee. I am using the following WebDav Exchange properties to retrieve to attendee for which the 'Send Meeting To Attendee' item option has been selected. Note that the following returns both the e-mail address and attendee display names. urn:schemas:mailheader:to http://schemas.microsoft.com/mapi/proptag/0x0E04001E My question is do you know of any property (possibly mapi or other) which can retrieve Calendar attendees regardless of the sending option. Many Thanks |

re: WebDAV How, What and Problems... http://schemas.microsoft.com/mapi/id/{00062002-0000-0000-C000-000000000046}/0x8238 is a read only property as far as i know. Did you try both propfind and sql search? If neither of those return them then i have no more trick up my sleeve. Sorry. |
|
2006-10-03 |
re: WebDAV How, What and Problems... Yes I did do the propfind. Anyhow thanks for trying at least you have given me an idea of what MAPI property I can use for my search. :) |

re: WebDAV How, What and Problems... I am using Exchange 2003 does the http://schemas.microsoft.com/mapi/id/{00062002-0000-0000-C000-000000000046}/0x8238 property exist for Exchange 2003? if not do you now the equivalent? |

re: WebDAV How, What and Problems... Hi Mladen, I will scrap the idea of retrieving the MAPI attendeee properties, its proving to be to complex and possibly not possible in Exchange 2003. I instead want to retrieve the contact properties such as name, email, phone number etc of contact(s) attached to a outlook appointment. Do you know of any WebDav properties which would allow me to do this? I would appreciate a response. thank you. Drew |

Drew
2006-10-05 |
re: WebDAV How, What and Problems... Do have any idea Mladen about how to do this? If it is possible to retrieve the Href property which points to the contact item then this property would be very useful. |

re: WebDAV How, What and Problems... I have tried urn:schemas:calendar:contacturl but that does not retrieve anything I have also used http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/0x0000853A but this retrieves the contact names and no other data, therefore do you know how to obtain the rest of a contacts data within the who is part of a contact within an appointment? could you reply ASAP, thanks |

re: WebDAV How, What and Problems... I hope i'm not a pest ): But I think you have misunderstood what I am trying to do, I want to be able to contact details from a contact contained within an appointment item and not in a contact item. Im having problem in getting the ContactUrl of the Contacts(contacts in the users contact folder) of a particular appointment. I tried using the namespace "urn:schemacs:calendar:contacturl" to get the contact details. But its returns nothing. Is there anyway to get the details of the contacts specified in the appointment. I can get the contact name buts that it I cannot retireve any further contact properties. I use the following property to get the contact names. http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/0x0000853A or I use http://schemas.microsoft.com/mapi/contacts Both get all the names of contact, but no further details hence I would to if there is anyway to retrieve further details using WebDav properties, what would be particularly useful to me would be to retrieve the contacturl, from which I would be able to use and get any necessary contact details I need. Any ideas/solutions? |
|
Mladen
2006-10-05 |
re: WebDAV How, What and Problems... Well i assume that your contact names are from people in your address book. you could search the contacts folder with contact names with sql for your returned names. for me it makes no sense that allcontact properties would be stored in the calendar object. think of the contact name as a key :) And no you're not a pest. :)) No worries. |
|
Drew
2006-10-05 |
re: WebDAV How, What and Problems... Thanks ;) The problem with that approach is that if I have many contacts with the same name then knowing which is the correct contact is not possible. If I am able to get a few distinct properties from the calendar contact such as e-mail address, phone number etc then my SQL would return me a more unique result which is the solution that I am looking for. Any ideas on how to get these few distinct properties? |
|
Mladen
2006-10-05 |
re: WebDAV How, What and Problems... Hmm... i get the URL of the contact in the contactURL if the contact is in the exchange. then i can simply query the contact object with it. I have no idea why you wouldn't be able to get it to. Are you setting that property when you're adding the contact with webdav? |
|
Drew
2006-10-05 |
re: WebDAV How, What and Problems... I dont add the contact with WebDav or add the contacturl in anyway, the scenario is that a user creates an appointment in outlook and puts in whatever data they choose, I then use WebDav to get the contact data. I want to do exactly what you have stated which is to get the contactURL of the item and to then query the contact object using the ContactURL but I am unable to retrieve the ContactURL any ideas on how to achieve this? :) If I am able to get the ContactURL then thats my problem sorted, just to make sure were on the same page the ContactURL property is: urn:schemas:calendar:contacturl Any suggestions? |
|
Drew
2006-10-05 |
re: WebDAV How, What and Problems... How can I set the contacturl? If I set the contacturl then would I be able to retrieve for all appointment contacts by using the property urn:schemas:calendar:contacturl ? |
|
Mladen
2006-10-05 |

re: WebDAV How, What and Problems... One FINAL thing. DO I need to do use a SQL query as part of the WebDav request? Also could you post your code as it will allow me to analyse what I am missing. I would appreciate it very much if you could do this. I dont want to pollute this forum with anymore posts. :) |
|
Mladen
2006-10-05 |
re: WebDAV How, What and Problems... There's no code really. I just use outlook 2003 i just do select all properties from calendar like. the select statement is a simple sql as described in "search" part of this article. and it's not a forum, It's comments of a blog post :))) |
|
Drew
2006-10-05 |
re: WebDAV How, What and Problems... Pardon me, I meant blog. :) Do I need to use a select query? Because at the moment I am using not using any sql in my webdav call and can retrieve all other properties that I require except the contacturl. Also within your sequel are you using the 'DEEP' search or 'SHALLOW' search? Could you post your contacturl result it would be interesting for me to see what the property result looks like and if it would be of use to me. |
|
Drew
2006-10-06 |
re: WebDAV How, What and Problems... mladen I am using an sql search, using a webdav search but I still cant seem to get the contacturl! Could you post a snippet of you code which shows how you retrieve the contacturl from an appointment and also the result. Can you reply to this? :) |

re: WebDAV How, What and Problems... Ok, i've looked into this thing a bit. First let's get something clear. What do you consider a contact? 1. An appointment attendee 2. On appointment tab in outlook there's a button in the lower left corner that says contacts? if 1. then those are people that you have in your exchange directory as users with mailboxes. Those can't have same names (at least i'm unable to give them same names in Active Directory). So it's either that full name or an e-mail to which you want to send a meeting request. those can be found in these MAPI proptags: PR_DISPLAY_BCC = "http://schemas.microsoft.com/mapi/proptag/x0e02001f" PR_DISPLAY_CC = "http://schemas.microsoft.com/mapi/proptag/x0e03001f" PR_DISPLAY_TO = "http://schemas.microsoft.com/mapi/proptag/x0e04001f" if 2. then you also can't have 2 contacts with the same name there. It'll simply show the first you choose. about getting that info take a look at this thread: http://groups.google.si/group/microsoft.public.exchange.admin/browse_thread/thread/7b1fb1719affa4d3/a45c1c5ce161d3b4?lnk=st&q=x800e001e&rnum=1&hl=sl#a45c1c5ce161d3b4 I'm preety much having the same issues. Oh and DO USE OutlookSpy. It's a great tool that integrates into the Outlook. As for urn:schemas:calendar:contacturl i'd like to thank you for finding a bug in my code. I had some values that i usually test with still hardcoded. When deleted i also get empty values for both fields. |

re: WebDAV How, What and Problems... Mladen, Is there any simple way to send a meeting request of a calendar item using webdav i.e. simulates the 'send' button option. I have looked at your example above but I do not want to create a copy of the item I simply want to send it and for the calendar item in my calendar folder to remain where it is. Is there anyway to do this? |
|
Mladen

re: WebDAV How, What and Problems... No you have to copy the item. Outlook does the same. because there are 2 items. An Appointment and a meeting request. |

re: WebDAV How, What and Problems... this is my send method of the MeetingRequest class: public override bool Send() { if (_Appointment == null) throw new ArgumentNullException("_Appointment ", "Appointment must not be null."); // save an appointment to calendar folder _Appointment.Send(); // copy an appointment for the meeting request Copy copy = new Copy(_Appointment.ItemURI, this.ItemURI, true); copy.ExecuteRequest(); this.MessageClass = "IPM.Schedule.Meeting.Request"; this.ContentClass = "urn:content-classes:calendarmessage"; this.CalendarMethod = Enums.CalendarMethod.Request; // Send a meeting request return base.Send(); } But don't tell anyone i've shown you this :))) Copy is the HTTP copy method. _Appointment is passed as an argument to the meetingrequest class. Appointment.Send() PropPatches the appointment into the calendar folder. MeetingRequest's send propPatches the meetingrequest into calendar folder and then move's it into the ##DavMailSubmissionURI## |

re: WebDAV How, What and Problems... Thanks Mladen, I should get everything working now, but could you just elaborate (code) on how to get the PUTS method working for sending attachments. This should be it for today ;). |
|
Mladen
2006-10-16 |
re: WebDAV How, What and Problems... you set the PUT's URI to the itemUri of your item and for body you put the byte array byte[] of your attachment. |
|
2006-10-16 |
re: WebDAV How, What and Problems... Mladen, you dont need to attach the attachments using PUT. Simply sending the meeting request automatically attaches the attachments :) Am I missing something or am I correct? |
|
Mladen
2006-10-17 |
re: WebDAV How, What and Problems... you have to put the attachment to the meeting request before you move it to the ##davsubmissionURI##. PUT simply uploads the attachment. |

re: WebDAV How, What and Problems... Mladen, When I create a copy of the original calendar item to send a meeting request it is sent correctly to all attendees but the meeting request is deleted (copied calendar item) from my calendar item. Therefore when an attendee accepts/declines an appointment an email is recieved by me but no calendar item is updated with the tracking information as the calendar item no longers exists becuase it was sent. Any ideas on how to get past this problem? I have followed the steps you suggested above. All I want to do is send a meeting request as you normally do through webdav and for the tracking bar to appear to track responses.... |

re: WebDAV How, What and Problems... Mladen, Thanks I already know about the resource. The resource however does not discuss sending meeting cancellations through WebDav. Do you have any idea how to do this? |
|
Mladen
2006-10-18 |
re: WebDAV How, What and Problems... to cancel a meeting request you need to set - http://schemas.microsoft.com/exchange/outlookmessageclass to "IPM.Schedule.Meeting.Canceled" - DAV:contentclass to "urn:content-classes:calendarmessage" - urn:schemas:calendar:method to "CANCEL" and send the meeting requsest update. |

re: WebDAV How, What and Problems... Mladen Yes you did a good job. Now I only need to work out how to send a meeting request which sends out the original item as a meeting request (as is done normally through outlook). Final hurdle. --- __ --- ___ --- |

Mladen
2006-10-19 |
re: WebDAV How, What and Problems... emmm... care to elaborate a bit more? |
|
2006-10-19 |
re: WebDAV How, What and Problems... Mladen, Well when you send a meeting request through outlook you simply click the 'send' button, this sends a meeting request to the attendee(s) and a 'tracking' bar is created in the item. Te attendee responds and the meeting request in the organizers mail is updated with the attendee(s) response. NO emails are sent or recieved, everthing is kept neat. All I want to do is replicate the above functionality in webdav. Any ideas? |
|
Mladen
2006-10-19 |
re: WebDAV How, What and Problems... Well i don't know the property URI that holds tracking info. if you find out do let me know. Well when you receive the meeting request reply you can get the appointment in your caledar that is associated with the meeting request's reply with athe property described in "Development problems and bugs" point 3 of this article. then you can update the appropriate appointment in your calendar with the tracking info. Outlook does the same i just don't know which properties get set. And i don't really have time at the moment to dig into this. I still want a look at your app once it's finished. :) |

re: WebDAV How, What and Problems... Mladen, One final thing. Is it possible to send a mail item using another mailbox location other then '##DavMailSubmissionURI##'? because this mailbox location is my problem as it deletes the calendar item. Is it possible to use another mailbox location which does not delete the calendar item? as I believe that this will be the solution to my problem. No more questions on this, I promise :) |
|
Mladen
2006-10-19 |
re: WebDAV How, What and Problems... Not that i'm aware of. ##DavMailSubmissionURI## is the folder for webdav to send mail. What do you mean it gets deleted from your calendar?? which item? An appointment for meeting request?? That shouldn't be happening. |
|
Drew
2006-10-19 |
re: WebDAV How, What and Problems... For example say that I dont want to create a copy of the calendar item I just want to send the meeting request of the item, then sending the meeting request of the calendar item using the '##DavMailSubmissionURI##' removes the item (meeting request) from my calendar. Should this be happening? This is the absoloute last hurdle to the solution i'm implementing and WebDav always finds a way of screwing it up for me..argggh... |

re: WebDAV How, What and Problems... Using that property is inefficient as it would require a search to find all items with the matching property and to then do an update, which is not the solution i'm looking. All I want is the 'send' operation to be replicated in webdav, which at this point in time looks impossible. Anyhow thanks for trying. |

re: WebDAV How, What and Problems... Mladen, I've cracked it. To set the 'Tracking' bar on the original calendar item from which a meeting request has been generated simply set the 'http://schemas.microsoft.com/mapi/finvited' property to '1' this will bring up the tracking bar and will capture all the respones made by all attendees although for some reason you need to view the e-mail response of the attendee first in your inbox before your calendar item is updated with the attendee response. Well there it is, something so simple can be so difficult to find out about. Happy programming :) |

re: WebDAV How, What and Problems... Mladen, I've got a bug which i'm having trouble with. When I save an attendee manually to a calendar item in outlook and I send a meeting request through webdav I get confirmation e-mails but when I save an attendee through webdav and I send a meeting request through webdav, I do not get the confirmation e-mails in my inbox. Do you know why this is? and how can i resolve this? |

re: WebDAV How, What and Problems... Hi I am using WebDAV to add appointments to shared calendars but get a 403 (forbidden error). When I change the status from BUSY to FREE then I no longer get the error or if I set an appointment in the past i.e. last year then I do not get this error. Apparently this is due to some Microsoft security update. Does anyone know of a workaround? TIA RS |

re: WebDAV How, What and Problems... Hi Mladen, I am new here and have read the entire thread, but haven't been able to sort something out. Perhaps it has been resolved, but I couldn't find it here. My problem is with setting the Due date and Reminder for a Task using webdav. I have used the code which is commonly available: xmlstr = "<?xml version=""1.0""?>" & _ "<d:propertyupdate xmlns:d='DAV:' " & _ "xmlns:e='http://schemas.microsoft.com/exchange/' " & _ "xmlns:b='urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/'" & _ "xmlns:f='urn:schemas:mailheader:' " & _ "xmlns:g='urn:schemas:httpmail:'" & _ "xmlns:h='http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/'" & _ "xmlns:i='http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/'>" & _ "<d:set>" & _ "<d:prop>" & _ "<d:contentclass>urn:content-classes:task</d:contentclass>" & _ "<e:outlookmessageclass>IPM.Task</e:outlookmessageclass>" & _ "<e:x-priority-long b:dt=""int"">1</e:x-priority-long> " & _ "<h:0x00008104 b:dt='dateTime.tz'>2005-09-27T00:00:00Z</h:0x00008104>" & _ "<h:0x00008105 b:dt='dateTime.tz'>2005-09-27T00:00:00Z</h:0x00008105>" & _ "<h:0x0000811C b:dt='boolean'>0</h:0x0000811C>" & _ "<h:0x00008101 b:dt='int'>0</h:0x00008101>" & _ "<h:0x00008102 b:dt='float'>0</h:0x00008102>" & _ "<i:0x00008503 b:dt='boolean'>1</i:0x00008503>" & _ "<i:0x00008502 b:dt='dateTime.tz'>2005-09-26T00:00:00Z</i:0x00008502>" & _ "<i:0x00008560 b:dt='dateTime.tz'>2005-09-26T00:00:00Z</i:0x00008560>" & _ "<f:subject>Test1234</f:subject>" & _ "<f:htmldescription>Fix this</f:htmldescription> " & _ "</d:prop>" & _ "</d:set>" & _ "</d:propertyupdate>" and other variations, but without success. What am I missing? I read somewhere that 0x00008104 is for Start date, 0x0000810f is for End date, and 0x00008105 for Due date. But when I send this over ( I also pass my exchange server name and mailbox), I get 400 Bad request errors. If I take the h and i tags, the Task gets created fine, but without those properties. Any ideas? Thanks a lot in advance. |

re: WebDAV How, What and Problems... Hi, interesting page but mostly way above my head! I'm debugging a problem where WebDAV is called from a VBScript to find a property of a mailbox, the meat of the query is this: <?xml version="1.0"?><a:propfind xmlns:a="DAV:" xmlns:d="urn:schemas:httpmail:"><a:prop><d:inbox/></a:prop></a:propfind> however it always returns 404 Resource Not Found. The script starts the query off with: req.open "PROPFIND", url, false where the "url" variable is in the form http://servername/exchange/mailbox/ - but it doesn't matter which mailbox I try The script is from microsoft, its actually the Auto Accept Agent, so I'm sure its coded right (!) but I don't know why Exchange is failing to respond - have you come across this before? Much appreciated, |

re: WebDAV How, What and Problems... Hi I am creating Appointment in Exchange using webdav but I have some problems. First. I cant create a recurrent appointment, I can modify an existent one. But the recurrence rule in new ones are ignored. If I create the appointment in outlook with a recurrence, then I can change it every time that I want with webdav. The xml that creates the appointment is this: <?xml version="1.0" encoding="utf-8" ?> <D:propertyupdate xmlns:D="DAV:" xmlns:f="urn:schemas:calendar:" xmlns:m="urn:schemas:httpmail:" xmlns:e="http://schemas.microsoft.com/exchange/" xmlns:dt="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"> <D:set> <D:prop> <m:importance>2</m:importance> <D:contentclass>urn:content-classes:appointment</D:contentclass> <f:busystatus>Busy</f:busystatus> <e:outlookmessageclass>IPM.Appointment</e:outlookmessageclass> <m:textdescription></m:textdescription> <m:subject>meeting</m:subject> <f:location></f:location> <f:dtstart dt:dt="dateTime.tz">2007-04-29T22:00:00.0Z</f:dtstart> <f:dtend dt:dt="dateTime.tz">2007-04-30T22:00:00.0Z</f:dtend> <f:dtstamp dt:dt="dateTime.tz">2007-04-30T08:36:40.0Z</f:dtstamp> <f:alldayevent dt:dt="boolean">1</f:alldayevent> <f:rrule dt:dt="mv.string"> <c:v xmlns:c="xml:">FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR;WKST=SU</c:v> </f:rrule> <f:instancetype dt:dt="int">1</f:instancetype> <f:recurtype>1</f:recurtype> <f:0x8214 dt:dt="int">1</f:0x8214> </D:prop> </D:set> </D:propertyupdate> I am forgeting something? Second. After creating the recurrent appointment, I can create exceptions, I can change the start/end date and subject but I cant change the exception label. Is there some especific property to set? Third. It's possible to delete the recurrence rule of an appointment? |

re: WebDAV How, What and Problems... Hi I can create an outlook contact by using webdav "PROPPATCH" with all details(personal,phones,addresses,emails...). But my problem is if the contact has Birthday & Anniversary dates, then I have to create the shortcuts or attachments of (birthday & anniversary) alldayevents in his note field using webDAV. If we open these shortcuts, it will open in IE. By manually allDayEvents are created like this : Insert -> Item -> Calendar(Look in) -> add shortcut or attachment But I have to add these shortcuts or attachments by using webDAV only. Please help me. I am searching for this since last month. Thanks in Advance |

re: WebDAV How, What and Problems... Jordi: 1. create the exact appointment you want in outlook and then look at it's properties with exchange explorer. it can be found in the exchange SDK. 2. What's an exception label? 3. yes it is. use <d:remove> in the propatch. works the same as <d:set> only you specify the properties to remove, Kumar: I'm on vacation until may 9th and i won't be at my work computer where i can check this, so if you can send me a reminder on the 9th and i'll see what i can find. |

re: WebDAV How, What and Problems... Hi, If we give the birthday or anniversary dates, then Outlook autometically creates Recurring Appointment events in Calendar folder and the shortcuts(links) are inserted in the contact's item field. Now I want to make the same above task by using WebDAV at the time of giving the dates of dirthday & anniversary. Even I created the exact Recurring Appointment event in Calendar by using WebDAV, I can not see the shortcuts(links) in the contact's item. I am also setting the Contacts field values in the Appointment Form. Thanks in Advance |

re: WebDAV How, What and Problems... Hi, I have 2 exchange users A,B. I created an outlook contact manually with all details including Birthday & Anniversary's dates in exchange user A. Then Outlook autometically creates 2 Recurring Appointments(Yearly) for Birthday & Anniversary's dates in exchange User A's Calendar folder and the shortcuts(references) are inserted into the contact's item. Now, I created the same contact's info by using WebDAV in another Exchange User B. I have also filled the Birthday & Anniversary's dates. But the Outlook did not create the 2 Recurring Appointments(Yearly) for Birthday & Anniversary's dates in exchange User B's Calendar folder and the shortcuts(references) are not inserted into the contact's item. How can we create the Birthday & Anniversary's Recurring Appointments(Yearly) in Calendar folder and insert the shortcuts(references) into the Contact's item using WebDAV? |

re: WebDAV How, What and Problems... you show how to save an appointment to the calendar.. can you show who you would retrieve calendar info about a person for a day. I'm struggling with this. I have the info coming back that i want, but can't get the all day events to show up. The query i'm sending i've not restricted at all. it brings back the alldayevent column, but it's always 0. when i look in outlook at the calendar, i see the all day event for a certain date, but that doesnt show up in the query. as soon as i change the calendar event to be from a certain time to another, it shows up. hope this isn't out of the scope.. thanks shannon |

re: WebDAV How, What and Problems... jvcoach23: if i remember correctly (haven't been doing this stuff for a while) you have to set your alldayevent to 1 and both start and end date to span exactly 24 hours. Nataraj: same as to the normal folders. you have to have permissions and you have to specify the correct URI. Adi: You can create the recurring appointments by setting the rrule property. I've shown an example in this post. I have no idea about refernce setting... |

re: WebDAV How, What and Problems... I was wondering if you might be able to help with a more specific issue? Here is the scenario: User's enter data into our tool, specifically Contact info and Task info. My job is to sync this data with exchange. The key piece here is that each Task or Contact has a unique ID, which is assigned by our tool. The old way we were doing this was using MAPI and Outlook. We created a user-defined field and populated it with data from our tool. Now we want to direct this input directly to exchange. So my question is, how can I create Tasks or Contacts at runtime and assign a user-defined field? Keep in mind that this is to run as a service application on the exchange server. Also, if the Tasks or Contacts are updated in our tool, I need to update that info in exchange? That is really where the unique key comes into play. How can I query exchange for the existence of a Task or contact given the unique id? Thanks Rob |

re: WebDAV How, What and Problems... i usually add custom properties to the DAV: namespace you can search the exchange like i specified in the post under search with the exchange dialect of SQL just add your custom property to the WHERE: SELECT ...

re: WebDAV How, What and Problems... Hello Mladen, Great topic and useful comments. I have some code for doing the meeting request and I noticed it's slightly different than yours. For example, in order to create the meeting request, I need to specify the uid of the appointment previously created. I see in one of the comments above that you don't do that. I think using the uid makes sense, if not, how do you relate the meeting request to the appointment? Regards, wf |

Mladen
2007-08-04 |
re: WebDAV How, What and Problems... yes you're right. when creating the appointment i specify the UID for it. then when i copy it, the UID is also copied. I'll probably have to update the article a bit... :) thanx for pointing it out. |

However, since the meeting request is moved in order to be sent, I get "HTTP Error 404 - File or directory not found." Any ideas how to get it from the appointment? For some reason mailheader attributes are not returned for the appointment. I must be missing something. Please, let me know if you have any ideas. Thanks in advance. |

re: WebDAV How, What and Problems... I am just verifying all attendees are there as expected in the organizer calendar for now. There are no TO or FROM properties in the organizer's meeting output. However, I noticed that I'm not getting them for the meeting request neither. I must have changed something in my code because I know I used to get those properties before. I'll take a look at my recent changes. Thanks anyways Mladen. |

re: WebDAV How, What and Problems... I'm able to get the TO and FROM properties again. However, for some reason I can get this only from the meeting request. Since the meeting request is sent to other attendees, it is not available anymore after a while, this make fail my verification with an HTTP 404 error. As a workaround, I'm explicitely inviting the organizer. This way the organizer will receive and keep a meeting request within his files. The side effect for this approach is that the organizer will appear twice in the meeting (as an organizer and as a required attendee). Does anyone has a better approach for this issue? |

re: WebDAV How, What and Problems... @bhj: Thanx! glad i could help. @wf: well sending an update is the same thing as sending an ordinary meeting request. get the existing appointment from the organizers calendar. set it's properties to whatever changed values you need and send the meeting request with the changed appointment. that's it. you still have to handle the TO property logic yourself. |

re: WebDAV How, What and Problems... i'm not sure if the attachments are also copied when you copy the appointment. i think you need to set the depth header value to infinity. if that doesn't work just attach the attachment to the original and copied attachment. |

re: WebDAV How, What and Problems... The solution I used was to attach the attachment to the appointment and to the meeting request. This way all agendas (even the organizer) will have the attchament associated to the appointment. The solution was as simple as that. Thanks Mladen, I really appreciate all the help you've provided me :) |

Creating recurring appointment Hi Mladen, I have successfully created a single appointment. Now I am trying to create a recurring appointment, but it still only creates 1 single appointment. I've even tried copying the rrule property of a real recurring appointment (from Exchange Explorer). Here is my xml (which only create a single appointment) <?xml version="1.0"?> <g:propertyupdate xmlns:g="DAV:" xmlns:e="http://schemas.microsoft.com/exchange/" xmlns:mapi="http://schemas.microsoft.com/mapi/" xmlns:mapit="http://schemas.microsoft.com/mapi/proptag/" xmlns:x="xml:" xmlns:cal="urn:schemas:calendar:" xmlns:dt="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:header="urn:schemas:mailheader:" xmlns:mail="urn:schemas:httpmail:"> <g:set><g:prop> <g:contentclass>urn:content-classes:appointment</g:contentclass> <e:outlookmessageclass>IPM.Appointment</e:outlookmessageclass> <mail:subject>testWebSvc</mail:subject><mail:htmldescription>body asdfasdf</mail:htmldescription> <cal:location>somewhere</cal:location> <cal:dtstart dt:dt="dateTime.tz">2007-08-17T12:10:50.4062500+10:00</cal:dtstart> <cal:dtend dt:dt="dateTime.tz">2007-08-17T14:40:50.4062500+10:00</cal:dtend> <cal:instancetype dt:dt="int">0</cal:instancetype> <cal:busystatus>FREE</cal:busystatus> <cal:meetingstatus>TENTATIVE</cal:meetingstatus> <cal:alldayevent dt:dt="boolean">0</cal:alldayevent> <cal:responserequested dt:dt="boolean">0</cal:responserequested> <cal:reminderoffset dt:dt="int">0</cal:reminderoffset> <cal:rrule><r:v xmlns:r="xml:">FREQ=WEEKLY;COUNT=5;INTERVAL=1;BYDAY=FR;WKST=MO</r:v></cal:rrule> <header:to>test1</header:to> <mapi:finvited dt:dt="boolean">1</mapi:finvited> </g:prop></g:set> </g:propertyupdate> Could you please help me find what I missed? Do I need to add any other property? (I only add "rrule", hoping this appointment would be recurring) Thanks very much. |

re: WebDAV How, What and Problems... this should be recurring in the creators calendar. at first glance i can't see what's wrong with it. create a new recurring appointment with outlook. then use either exchange explorer or outlook spy and compare it's properties with yours. |
|
wf
2007-08-20 |
re: WebDAV How, What and Problems... Hello Mladen, When you compare the properties using exchange explorer, do you do it in the exchange server or in the client machine? The reason I'm asking is because Windows XP is not listed as a supported OS in the download page. Regards. |

re: WebDAV How, What and Problems... Hello Mladen, I'm back with questions regarding accepting meeting request as you predicted it. 1. Is it possible to reply meeting request using webdav? I only found a topic where you do it mixing webdav and OWA commands. I want to emphasize that what I want is to create the reply meeting request and not to process it. 2. How do you get the property value mentioned in "dev. problems and bugs - step 3"? I guess I need to do something like this: <?xml version=\"1.0\"?> <a:propertyupdate xmlns:a=\"DAV:\" xmlns:n1=\"http://schemas.microsoft.com/mapi/id/\" ... <a:set> <a:prop> <n1:0x23>Test Text</n1:0x23> <--- not sure about this line ... Thanks in advance. |

re: WebDAV How, What and Problems... heya! 1. yes it's possible to reply to meeting requests with WebDAV. I'm in the porcess of writing a post about this that will go up today or tommorow It's acctually quite a tricky little bugger. 2. <?xml version=\"1.0\"?> <a:propertyupdate xmlns:a=\"DAV:\" xmlns:n1=\"http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}" > <a:set> <a:prop> <n1:x23>Test Text</n1:x23> ... you can't have a 0 in front of the x in the property name like i explained in Development problems and bugs 1.

re: WebDAV How, What and Problems... i didn't have much luck. I can get it to create an appointment (non -recurring) and also, using your help (THANK YOU) I can create a recurring appointment. but it doesn't show up as recurring in outlook. what i mean is. using webdav I create a recurring appointment (of instance type 1) and exchange creates the title-2.eml file of instance type 2 automatically but no recurrring appointments show up! any tips? |
|
Mladen
2007-08-28 |
re: WebDAV How, What and Problems... what are you reffering to as instance type? in your RRULE you have to set FREQ=N or other number, where N means: "0" = Daily; "1" = Weekly; "2" = Monthly; |
|
jim
2007-08-29 |
re: WebDAV How, What and Problems... but it shows up as a string representation then? examples show this FREQ=WEEKLY;COUNT=10;INTERVAL=1;BYDAY=WE;WKST=SU are you saying that I should say freq=1 ? |
|
jim
2007-08-29 |
re: WebDAV How, What and Problems... maybe I should be more clear :) with to regard to your code : _RecurrenceType = Enums.RecurrenceType.Daily; could you post your Enums class? thanks so much! |
|
Mladen
2007-08-29 |
re: WebDAV How, What and Problems... yes you're right. had a bug in my code. you have to put a string in there and i was putting a number I haven't done much work with recurrence so i'm not familiar with all it's quirks :) but it looks like you have to create as many appointments as you need with the first one (the master) having these 2 properties set: http://schemas.microsoft.com/exchange/patternstart http://schemas.microsoft.com/exchange/patternend try it and let me know. i'm in muddy waters here too... |
|
jim
2007-08-29 |
re: WebDAV How, What and Problems... so are you saying that we must create EACH appointment individually? create the master, and then create all of the other ones? using a seperate request for each??? thanks for your quick replies sir :) |
|
Mladen
2007-08-29 |
re: WebDAV How, What and Problems... looks like it... since webdav is totaly undocumented i can only guess how the inner workings truly work. :)) if you find a better way do let me know. |

re: WebDAV How, What and Problems... could you still post your enums class? |

re: WebDAV How, What and Problems... sure: public enum RecurrenceType { Daily = 0, Weekly = 1, Monthly = 2, Yearly = 3 } just remembered: try setting recurrenceidrange to 1 on the master appt public enum RecurrenceIDRange { None = 0, ThisAndFuture = 1, ThisAndPrior = 2 } |
|
jim
2007-08-29 |
re: WebDAV How, What and Problems... What does the range do? I don' t see it in the xml of a recurring appointment (I mean one i created in outlook to check format etc..) |

2007-08-29 |
re: WebDAV How, What and Problems... specifies if the range is set for the future or for the past. |

re: WebDAV How, What and Problems... I figued it out. You don't have to create separate instances for each appointment. Just create the master appt, BUT you must include the timezone in the create xml (request) looks like this. <cal:timezoneid dt:dt="int">11</cal:timezoneid> where the number (11 in my case) is your time zone. listing of timezones http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/_cdosys_cdotimezoneid_enum.asp w000t thanks for helping we work through it. |

re: WebDAV How, What and Problems... I'm having trouble changing a single instance of a recurring meeting after the original recurring meeting is created and the request is sent. I've tried creating new meetings of instancetype=3 but that just shows another single appointment in outlook. I've also tried updating the exdate and rdate in existing master appointment, but that always returns 400, bad request. Do you know how this can be done? |

re: WebDAV How, What and Problems... Using the timezone, can you create the appointment (without any sort of recurrence)? try creating a single non-recurring appointment first that includes the timezone. does taht work? |

re: WebDAV How, What and Problems... now I have a question.. does anyone know if you can add an appointment (as admin) to a regular user's mailbox? or do you have to traverse the user list and call up passwords for each indv user? |

re: WebDAV How, What and Problems... if you can access a mailbox you can add stuff to it. all you need is to give proper credentials to the http request |

re: WebDAV How, What and Problems... hi, Jim, i don't make recurrence. I want to send only an appointment. For this, I want to give the current hour and the system make itself the translation to UTC hour. I have read we must use "<cal:timezoneid dt:dt=""int"">4</cal:timezoneid>" for this, but it don't work. |

wf
2007-10-30 |
re: WebDAV How, What and Problems... Hello Angel, I had trouble with this before. Apparently, you need to take care of adjusting the dates before creating your appointment. You should be asking yourself now what's the purpose of having the timezoneid element then, well apparently this is needed to creating recurring meetings as someone stated before. Besides that, I don't see a utility. |

re: WebDAV How, What and Problems... Hi, I wrote an application(VB.Net) with XmlHttp object (COM) to do some operations in the exchange server. This application works fine. Now , I want to write the same application with HttpRequest(.Net) instead of XmlHttp, but always When I try to get a response from a query, I get the following error : The remote sever returned an error:(404) Not Found. Here some lines of the application: '***** Save the attachment ******* ' sUrlAttach is the url of an attachment in the exchange Dim myreq As Net.HttpWebRequest = Net.WebRequest.Create(sUrlAttach) myreq.Method = "GET" myreq.Credentials = New System.Net.NetworkCredential("****", "*****") ' The error occures after this line : Dim o_resp As Net.WebResponse = myreq.GetResponse() Dim instream As Stream = o_resp.GetResponseStream() Dim sr As StreamReader = New StreamReader(instream) Dim sResp As String = sr.ReadToEnd() Dim fs As New FileStream("C:\" & attchFileName, FileMode.Create) Dim w As New StreamWriter(fs) w.Write(sResp) w.Close() fs.Close() Like I wrote before, This is just one example ,and I have this problem with others querys too.

re: WebDAV How, What and Problems... hello i'm creating, updating and deleting appointments with webdav. for meeting requests i'm also sending out notifications to the participants. it's all working fine except that when i get a response from one of the praticipants (accept/deny/tentative) and i delete that response my appointment gets deleted also... maybe i need to be a little more specific: i create an appointment / meeting request with webdav, then the other user accepts it (manually) in his/her outlook client (thus sending back the response) and i open and delete the response (manually) in my outlook client - at that point my (original) appointment gets deleted, too. i think the problem must be something around what you called "AppointmentAndMeetingRequestResponseConnector" :-). when i don't set a value for this property the appointments don't get deleted - but the answers don't get reflected in my appointments either (always "no responses have been received"). when i set the property the answers get reflected, but then the appointments gets deleted, too. here's the xml i use to create a new appointment: <?xml version="1.0"?> <dav:propertyupdate xmlns:dav="DAV:"> <dav:set> <dav:prop> <cal:busystatus xmlns:cal="urn:schemas:calendar:">Busy</cal:busystatus> <mapif:0x23 d4p1:dt="bin.base64" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:mapif="http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/">OAA4ADEAZgBlAGUAZgBmAC0AYgA4ADIAZAAtADQANQA1ADMALQA5AGEANgAxAC0AYgAwAGIAZgBkADIAZgA2AGEAZQA0ADcA</mapif:0x23> <cal:instancetype d4p1:dt="int" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:cal="urn:schemas:calendar:">0</cal:instancetype> <mapi:finvited d4p1:dt="boolean" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:mapi="http://schemas.microsoft.com/mapi/">1</mapi:finvited> <cal:meetingstatus xmlns:cal="urn:schemas:calendar:">Confirmed</cal:meetingstatus> <cal:responserequested d4p1:dt="boolean" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:cal="urn:schemas:calendar:">1</cal:responserequested> <cal:dtstart d4p1:dt="dateTime.tz" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:cal="urn:schemas:calendar:">2008-01-10T18:17:56.472Z</cal:dtstart> <cal:dtend d4p1:dt="dateTime.tz" xmlns:d4p1="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:cal="urn:schemas:calendar:">2008-01-10T19:17:56.472Z</cal:dtend> <mail:subject xmlns:mail="urn:schemas:httpmail:">test012</mail:subject> <cal:location xmlns:cal="urn:schemas:calendar:">loc</cal:location> <mail:htmldescription xmlns:mail="urn:schemas:httpmail:">TEST</mail:htmldescription> <header:to xmlns:header="urn:schemas:mailheader:">xxx</header:to> <dav:contentclass>urn:content-classes:appointment</dav:contentclass> <exch:outlookmessageclass xmlns:exch="http://schemas.microsoft.com/exchange/">IPM.Appointment</exch:outlookmessageclass> </dav:prop> </dav:set> </dav:propertyupdate> any idea what might be the cause of this behaviour? thanks in advance, best regards ps: i know the namespaces are ugly; still investigating why this happens (http://www.tek-tips.com/viewthread.cfm?qid=1440492&page=1). but i don't think that has anything to do with this problem. |

re: WebDAV How, What and Problems... unfortunately that didn't helped :-( there is another post up the page by john collins who seems to have been struggling with the same problem - but there's no solution so that doesn't really help either... i have compared an appointment i created with webdav and one i did with outlook using a PROPFIND with "allprop" and the structure is identical - that way i don't see the mapi properties though... i'm setting all these properties when creating an appointment: AllDayEvent BusyStatus CalendarId-Mapi0x23 DateTimeStamp InstanceType fInvited MeetingStatus Priority ReminderOffset ResponseRequested Start End Subject Location Body To Cc and before sending the meeting request i now also set the CalenderUID (to the value of the CalendarId-Mapi0x23) anything else that must be set or that shouldn't be touched? how exactly do i need to set the CalendarId-Mapi0x23 as this is a base64 value (i use Convert.ToBase64(Guid.NewGuid().ToByteArray()))? to what value do i need to set the CalendarUID; does it has to be the same as the CalendarId-Mapi0x23? thx for any support, best regards |

re: WebDAV How, What and Problems... Hello, I'm using WebDAV to do some processing on message items inside some user's Inbox. I retrieve a chunk of mail message href(s) using SEARCH method of WebDAV, then set a custom boolean property on each retrieved message item to label it as processed. After that, when i do a WebDAV SEARCH request on the Inbox asking for the message items those who does not have this property set on them, the returned response has 0 row count.. here is an example of the select statement: <?xml version="1.0"?> <D:searchrequest xmlns:D = "DAV:"> <D:sql> SELECT "DAV:contentclass", "DAV:displayname","urn:schemas-mydomain- com:processed" FROM "http://assemwin2003/Exchange/Assem/Inbox/" WHERE "DAV:ishidden" = false AND "DAV:isfolder" = false AND "urn:schemas-mydomain-com:processed" <> CAST("true" AS "boolean") </D:sql> </D:searchrequest> if i changed the condition to : ... "urn:schemas-mydomain-com:processed" = CAST("true" AS "boolean") ... it returns me -successfully- the messages who i set the custom property on. So, any body can help on how to construct the search query to return only the message items who does not have this property at all ? Thank you in advance. |

re: WebDAV How, What and Problems... @Sandro Rudin: i usually set the calendarUID to a guid. and allprop won't really return all properties. only the default ones for the namespace. you have to manually add all props to propfind. but honesly i have no idea on how to help you on this. if you do find the answer do post it here, @Assem: "urn:schemas-mydomain-com:processed" = CAST("false" AS "boolean") |

re: WebDAV How, What and Problems... oh by the way when i wanted to set my custom properties i always put them in the DAV namespace and not my own since i foundout that my handling of my own namespace was a bit flaky by the search engine. you can try where yourProp is null but i don't know if that will work since i'm not familiar with how exchange parses sql queries |

re: WebDAV How, What and Problems... just for the records: i did find a solution and like to share it with you as i think that others might stumble over it as well. to be honest: i didn't find it out myself but got the answer from henning krause. here's the link to his blog addressing the issue i described a bit up the page (and if you check the toc you can find many other interesting posts about webdav and exchange so you might find the solution to other problems there as well): http://www.infinitec.de/articles/exchange/moreonmeetingandmeetingrequests.aspx best regards |

re: WebDAV How, What and Problems... Hi there! Have you ever worked with this section when you're trying to create contacts? "<e:extensionattribute1>User Data 1</e:extensionattribute1>" + "<e:extensionattribute2>User Data 2</e:extensionattribute2>" + "<e:extensionattribute3>User Data 3</e:extensionattribute3>" + "<e:extensionattribute4>User Data 4</e:extensionattribute4>"; I'm really not sure how it works. I'm trying to add more user-defined fields of contact information, so that the user can group/sort the contacts by those fields. I have tried using "<e:keywords-utf8>"<x:v>" + UserDefinedField1 + "</x:v>" + "<x:v>" + UserDefinedField2 + "</x:v>"+</e:keywords-utf8>) to create categories. But if i have more than one categories, it gets quite messy. I hope I'm making sense here. Could you help? ~dave |

re: WebDAV How, What and Problems... Thanks for many great articles on the topic. I am using webdav to update an exchange calendar which subsequently updates a blackberry. The information I get is from a 3rd party system, so I have no control over that :( My Question is: I get the data from the remote system as an appointment, then a list of dates. Is it possible to create a recurring appointment using the rdate field only, or do I need to specify a rrule as well? If I do need an rrule, is there any easy way to obtain a rule from a list of dates? Thanks in advance, Chris |

re: WebDAV How, What and Problems... I want to create a calendar event which is say starting as 11:00 PM on 13th March and ending at 1:00 AM on 14th March. I want this calendar event entry to get added on both the days i.e. 13th March & 14th March. To achieve this, do I need to send 2 queries to the Exchange server or Exchange server will handle this scenario on its own ? When I am using the below info for calendar event creation, the entry is getting created only for 13th March and not for 14th. What should be done so that the entry gets created for 14th also ? " <d:location>" + encodeAmps(location) + "</d:locatio " <d:dtstart d:dt='dateTime.tz'>" + startZuluTime + "</d:dtstart>" + " <d:dtend d:dt='dateTime.tz'>" + stopZuluTime + "</d:dtend>" + " <e:subject>" + encodeAmps(subject) + "</e:subject>" + " <e:htmldescription>" + encodeAmps(details) + "</e:htmldescription>" + " <j:to>" +strRequired + "</j:to>" + " <j:cc>" + strOptional + "</j:cc>" + " <d:instancetype d:dt='int'>0</d:instancetype>" + " <d:busystatus>BUSY</d:busystatus>" + " <d:alldayevent d:dt='boolean'>" + allDayEvent + "</d:alldayevent>" + " <d:meetingstatus>TENTATIVE</d:meetingstatus>" + " <d:lastmodified>" + lastModTime + "</d:lastmodified> " |

Attendee response information from Meeting Request Hi Malden, I am using Exchange 2003 and am trying to query Exchange Store for Attendee Responses having the meeting request item and its attendees information stored in CC and TO properties of the meeting request. I assumed that it is stored somewhere in the Meeting Request itself but I was not able to figure out which property holds the info. Outlook updates the info in the Tracking tab of the appointment so I though they should be somewhere associated with the original meeting request. Could you please help me on this. Thanks. I would also like to thank you for your instructions above that really helped me in my project. Mansour |

re: WebDAV How, What and Problems... Dear Mladen, First of all Thanks a lot for your above suggestions which helped me to generate meeting requests to different users in my project. But now iam having a problem. From each user, iam taking their network username and password as input and then iam generating meeting requests from their outlook.If they give three times wrong username and password, then our company domain will block their network login for 1 hour.So what my quest is that can i check anywhere user's username and password before sending meeting requests.And one more question is that can i change users from email id. Please help me in this regard ASAP... |

re: WebDAV How, What and Problems... There is no support for using WebDAV for Meetings, Tasks or Recurring Appointments. You may be able to get some basic functionality, however it will not work in all cases and you will end-up at a dead end. For functionality in those ares, consider using Exchange Web Services (EWS) or call CDOEX code in a COM+ service or web service. I support the WebDAV API against Exchange - please review my blog: https://blogs.msdn.com/webdav_101/archive/2008/05/01/whats-not-supported-with-webdav.aspx Thanks, danba |

re: WebDAV How, What and Problems... Hi, I am using WebDav protocol to create/send/delete Appointments/Meeting requests on Microsoft Exchange server 2003 SP2. I see that every day few appointment items vanish from the organizer's calendar without anyone explicitly deleting them. The items get deleted in bulk i.e, 15 - 20 every day. The software which creates the meeting requests/Appointments is written in Java and operates under Solaris 10 operating system. This is also happening with few attendees who say their calendar items are missing once they accept them. Am I doing something wrong? Please help in finding the issue here? Advance thanks for the help. Ramana |

Query webdav for x65e00102 (PR_SOURCE_KEY) in where clause I am facing issue to fetch x65e00102 (PR_SOURCE_KEY) with webdav.

re: WebDAV How, What and Problems... After I debugged the issue. We're going to get a MAPI_E_TOO_COMPLEX (which bubbles up as your 422) if you search for that key. The error is coming from here: 0x65E00102 = PR_SOURCE_KEY So it is recommended to find a different property to search on. It is suffering from the above limitation when we referenced with WebDAV code. Recommended workaround: ======================= The only other workaround here would be to use some other identifier for a message, perhaps dav:id? It doesn't look like EntryID will work without some major change in Exchange. So we need to make use of PermanentURL property. |

re: WebDAV How, What and Problems... Hi ramana. You have to set the property 0x8218 in the appointment propertyset (http://schemas.microsoft.com/mapi/id/{00062002-0000-0000-C000-000000000046}/0x8218) to 1. This is the ResponseType property and a value of 1 means Meeting Organizer. If you don't set this property, Outlook will remove this appointment after you get a meeting response from one of the attendees. http://www.infini-tec.de/post/2007/07/More-on-meetings-and-meeting-requests.aspx |

re: WebDAV How, What and Problems... first fetch the the uid of the master Recurring appointment and using this uid u can fetch all the instances by using the search method . in where clause keep the condition Where urn:schemas:calendar:uid = uidString AND Not urn:schemas:calendar:instancetype = 1 Select " DAV:href + "\"urn:schemas:calendar:location\" AS location, " + "\"urn:schemas:httpmail:subject\" AS subject, " FROM Scope('DEEP TRAVERSAL OF \"\"')" + " WHERE urn:schemas:calendar:uid = uidString AND Not urn:schemas:calendar:instancetype = 1 |

re: WebDAV How, What and Problems... Hi vasa, Thanks, i can get the instance by the way just as you said. Another problem. I'm working for sync data of exchange store to my DB. I have completed the exchange2007 with webservice. Now i working on sync recurring item in exchange2003 sp1 with webdav. I try to use search method to get the recurring master item. With outlook2003, owa2003 and outlook2007, i do the same thing that i create a recurring master, produce an exception by update its subject. But i get the diffrent results with diffrent client. With outlook2007, i get the master item with no RRule property. And i can't get the instances with serach method . With outlook2003, owa2003, i get the master with exactly RRule property. And i can get the instances with serach method too. I'm confused. Does anyone know about it? Advance thanks for the help. Ying |

re: WebDAV How, What and Problems... When I set a contact birthday in Outlook and then retrieve it through webdav, I actually get the date before the date I set in outlook, with another string attached, for example: 2009-05-15T22:00:00.000Z for a birthday on the 16th. I can only assume this is some timezone information but how can I deal with this generically? |

re: WebDAV How, What and Problems... Hi, I am executing he following steps to create a meeting request: - Create an appointment in your calendar folder (point 2) - Create the Appointment in Drafts folder with a different URI - set the http://schemas.microsoft.com/exchange/outlookmessageclass property to "IPM.Schedule.Meeting.Request" - set the DAV:contentclass property to "urn:content-classes:calendarmessage" - set the urn:schemas:calendar:method property to "REQUEST" - PROPPATCH (save) the meeting requests properties - Attach any Attachment with PUT Request - MOVE the item to ##DavMailSubmissionURI## All the steps execute successfully except the last one (MOVE to ##DavMailSubmissionURI##). We are consistently getting "Operation timeout" error when we submit the MOVE request. Even COPY method is giving the same timeout error. Is there any setting on exchange to enable the sending from the ##DavMailSubmissionURI## folder? Any advice is greatly appreciated? Thanks, Furqan |

re: WebDAV How, What and Problems... Hi to anyone who makes it this far down the page.... I created my own implementation of the Request class but I was getting a 400 Bad Request error when attempting to use it. The problem was that I had mixed up the order of _HttpWebRequest.ContentType and _HttpWebRequest.Headers. I was assigning the ContentType and then setting the Headers property which was overwriting the previously set ContentType since it is stored in the Headers property as well. As a result, I created a for-loop to to add each header property. I guess you could also just set the Header property first. |

re: WebDAV How, What and Problems... Hi, I would need your help. We are facing one issue. We have our application which reads all unread email items from a mailbox using Web Dav and does some processing. It works fine for almost all the emails but only for the emails which a subject line like - Test + Email , i.e having "+" in the subject line do not work. While forming the mail item , it gives out the error (404) Not Found. And the URI would look something like - http://XXXXX/exchange/XXX/Inbox/Test%20+%20Email.eml. Need your help urgently. THnx Dhipak |

re: WebDAV How, What and Problems... @Dhipak: Install the Exchange Explorer from the Exchange SDK and explore your mailbox with it. That should give you the correct url your mail has. other option could be that you're going through an ISA server that is too strict with characters that it lets through. Also try looking directly at the HTTP traffic with a network sniffer like WireShark or Fiddler. that could also provide some answers. Also the URL encode for the + is %2B. so you can try to encode that too by hand. |
