You do know they document this stuff?

Don't know if this will work.  If you need to modify the messages, I
guess the proper way is to use WebDAV.  It has a PROPPATCH method that
will allow you to modify properties of existing objects.   Microsoft's
documentation: 

http://msdn.microsoft.com/en-us/library/aa493854(EXCHG.80).aspx

But it will of course be a lot easier to integrate it into Gnus if
replacing the message using IMAP works.  Looking forward to the results
of your experiments :-)

AFAIK, other applcations integrating with Exchange, like Evolution, use
WebDAV for things like this.   There's probably a reason....
