I have several users that are connecting to a Domino server using POP in Outlook 2007. One of the users (only one) gets prompted for his password frequently. His Outlook Profile has been recreated twice but the problem persists. IMAP is not an option unfortunately. The computer is running XP Pro. I thought that it may be a corrupt Windows profile, but that is a lot of trouble to go through for something that might not fix the issue. Has anyone encountered this before?
