Well, I’ve run into an interesting one here. I have a client who is running Office 2007 with Vista (he also has a BlackBerry Pearl). Some of the items that he deleted from his inbox will show up in the deleted items folder as duplicates. One of the duplicates shows as read and the other as unread. I have compared the headers on the duplicate messages and have confirmed that they are in fact the same message (headers are identical). The duplicate issue does not happen with every item, or even with every sender. It does not always happen with the same sender either. Meeting requests will also duplicate themselves once they are deleted. We have been able to confirm that this is not an Exchange issue (we are running Exchange 2003). We have moved his mail object to a different exchange server, cleaned the client and server rules. We even recreated his mail object. So far nothing has worked. I am not sure if this is a known issue with Office 2007, but I have been unsuccessful trying to find answers on Google. I have yet to hear from anyone that they have run into this same issue. Anyone have any ideas as to what is going on here?
Thanks
S
