I installed Office 2007 (original!) on Windows XP (fully updated).

I configured it to use all my mail accounts, some of them with IMAP instead of POP. It's the same configuration I had with Outlook 2003.

The problem is that Outlook 2007 crashes at start up as soon as I have an IMAP account (or more) configured.
If I have only POP accounts or nothing at all there is no problem.

Any idea?
