I just converted a user from Outlook Express to Outlook 2007 SP2. He has multiple POP3 accounts setup and they all converted fine along with all his settings. We have it set to leave a copy of the messges on the server for 10 days. Now everytime he closes Outlook and reopens it it will re-download all the messages from the server giving him multiple copies of the same message. Outlook Express never did this. This is actually happening on 2 differnet PC's and I am not sure why, we have all the Office and Windows updates on the PC's. Anyone ever some across this??
