I have the same issue I think. I just have one single email account to check - and I want to use IMAP. However I also have two folder displayed:

• The personal folder/account (which only supprts POP)
• The IMAP account

As far as I have read in posts. Outlook is still very crappy in ways of IMAP.

• No Outbox for IMAP -> everything ends up in the POP outobx
• Can't hide the mail folders in the POP section ...
