I can't seem to make the "Delete duplicate messages" nor the "Flag Duplicate messages" to work. I had trouble with Outlook downloading my entire inbox and it did it multiple times. I have 6 copies of 3,000 emails. They have the same sender, receipent, date, and size. The utility scans the folder but doesn't see any duplicates. I have Outlook 2007 with SP2, Windows XP, MS Explorer 8. Am I doing something wrong?
