Hi I have Outlook 2010 configured with multiple accounts. But all my gmail accounts are sending two copies for one email. All of them are IMAP. I went through this article - http://social.technet.microsoft.com/Forums/en/outlook/thread/bc6defe9-cdd4-4ff8-910c-93793c796100 and it does not seem relevant to me. I have no extra rules. Also interesting thing is this is not happening with either hotmail account or with another POP account.
Any clues on what's going on?
