Microsoft Exchange Bugs

IMAP requires messages to be immutable. Exchange IMAP changes the existing mails sometimes:

Exchange sometimes messes up sequence <-> UID mapping. Especially when doing a "UID FETCH n:* FLAGS" immediately after a new mail has arrived (EXISTS reply was received) it often sends sequences higher than the EXISTS reply and also sends UIDs belonging to wrong (existing) sequences. (2010 SP1)
