When synchronizing cache imap folder with groupware content I receive the error message below. I have tried to delete the account and make a new several times and done "Troubleshoot IMAP Cache ..." many times too. The problem appears as soon the folder has been tagged as calendar. I don't have problems with other calendar folders.

The imap account is in a Microsoft Exchange 2000 IMAP4rev1 server version 6.0.6603.0
