WebDAV change appointmentWhat is the best way to change existing appointment?
Let's say we stored urn:schemas:calendar:uid and want to update it and add new property or something. Thanks, Dmitriy Hello Dmitry,
if you have the DAV:uid, you'll have to perform a SEARCH on the calendar to the the url of the apointment. After that you can do a PROPPATCH. Appointments are somewhat special, because Exchange 2003 SP2 and later will recreate it under certain circumstances, effectively modifying all other ID properties (EntryId, etc). For all item types but appointment I would rather store the permantUrl property.

If I understood it correctly, we CAN use DAV:uid for appointments ONLY but NOT for other items? Or it would be safier to store http://schemas.microsoft.com/exchange/permanenturl as our appointment ID? What about DAV:href? Will it be recreated?

DAV:href will change when you change the subject in Outlook. http://schemas.microsoft.com/exchange/permanenturl will does not change unless the item is moved to another folder. The permanent url is constructed from the MAPI EntryID. DAV:uid is a string property - I would assume that it suffers from the same disadvantages as the DAV:id property (http://support.microsoft.com/kb/320749): Exchange string comparisons are case-insensitive. For appointments, I usually use the property http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/0x3, which is a binary property used by Outlook accros mailboxes to correlate meetings and meeting requests (http://support.microsoft.com/kb/899919). If you create the appointment yourself, you can set this property to an arbitrary value (I use Guid.NewGuid().ToByteArray() and convert the result to a Base64 encoded string). PR_SearchKey should also be suitable for identification (Property tag 0x300B0102).

this happens when you try to read an Exhange response containing these properties into an XmlDocument or use an XmlReader. Unfortunately, Exchange returns invalid XML in this case. See http://www.infinitec.de/articles/exchange/creatingwebdavrequestswithxmlreaderwriter.aspx for a workaround.

I would guess the search key remains stable as long as Exchange does not recreate the element. I have no clue if it remains stable after this happens. But according to the KB article I mentioned earlier, http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/0x3 is a stable property.
