I've been trying to figure this out for about two weeks. I'm able to create email items in people's folders, read the folders, all that stuff but for the life of me I can not get anything to work with the calendars.
I can provide examples of the XML I'm sending to WebDav but hoping someone out there has done this and has an example?
I did this in a Java program a few years back, and the way I did it was to PUT a VCALENDAR document into the folder. One quirk is that the VCALENDAR had to be enclosed within an RFC822 message. It's a bizarre combination of WebDAV, email, and iCAL/VCAL, but it worked at the time on Exchange 2003 hosted at Link2Exchange.
I'm sure there is an easier way, but this is what worked for me. Below I show a tcpdump packet trace of what happened. You should probably use ngrep/tcpdump on your own Outlook/Entourage client to see what it does.
Note that "Cal2" is the name of my test calendar folder. You'd use "Calendar" for the main calendar folder.
