I was too early with my assumption. It is not working, just got the same Error Message for the Drafts- and the Sent-Folder. When looking at it, one message seems to be added 100s of times, until Mailmate detects its error.
Any Ideas what might have caused this? Exchange is a bitch, yes, but I doubt that it is just now coming out of nowhere...
