OK-Let's see if I can paint the picture.
A user has an email account on an Exchange 2003 server and uses outlook (not express) on an office workstation. There are rules for moving inbox items to folders within Outlook. There is also a spam filter add on in Outlook.
Once Spam has been filtered and rules have run, incoming messages are forwarded to the Blackberry. The problem is that every once in a while, an old email item, from the Outlook inbox, that may be several months to years old, will all of a sudden appear in the Blackberry's inbox, among the fresh mail messages. The item does not appear in the sent items in Outlook either. Any ideas?
