[Dovecot] Outlook 2003 - Disappearing favorite folders

Hello all,

I'm having an issue with Outlook 2003, where favorite folders seem to disappear. Specifically, they are subfolders of the Inbox. The Inbox favorite folder stays there without a problem. Any clues as to what the problem may be? With the previous IMAP server (courier I believe) this wasn't a problem...so it leads me to believe that Dovecot might be the problem. I'm working with Dovecot 1.0.rc28

Thanks, Phillip
