How to edit a reccur instance using WebDav

Well, this is a very tricky area to be modifying/creating appointments with
WebDAV. There are quite a few of the required properties that are not
documented for use and normally developers will just try to reverse engineer
the correct properties for their solutions. There is a lot of complexity in
this area and this is the primary driving factor for the following article:

Available support for applications that use the WebDAV protocol to access
Exchange 2000 Server or Exchange Server 2003
http://support.microsoft.com/kb/920134

There has been a lot of discussion around this area, and a lot of the issues
that you may be encountering are probably related to not having all of the
required properties set correctly. As you may already know, WebDAV is a
protocol and not a API with business logic, so your forced to set all of the
correct properties yourself, which may work and in other instances may not.

Hope this helps.

Hi
I created an recurring appointments through OWA without any attendees.
Now I want to edit one of the instace of the appointment using WEBDAV.
I am getting successfull message with WEBDAV but when I try to open
the meeting instance I have updated with selection of Open the series,
I got message. "The item could not be found. It may have been
deleted.". Can you please provide me the WEBDAV request I need to
write to update instance of recurring meeting request.
I just want to change the subject or Start datetime of the reccur
meeting instance.
