I am so frustrated because in the past 2 weeks or so, I am receiving duplicates of emails. It is sporadic and happens almost daily and I have not changed any settings that I can remember. I have Windows 7, IE8 and Outlook 2007 - I have my settings to keep email on the server for 7 days and have not changed this either. It seems a mystery to me and if anyone could make a suggestion as to why this is happening and what I can do, I would greatly appreciate it.

I had the same issue when I was using Outlook 2003 IMAP. I am not having that particular problem now that I am using an IMAP account in 2010.
