I recently bought a new computer and I imported my pst file into Outlook 2003. I have a yahoo business email account and after the import I was receiving over 100 MB of old email. Outlook had downloaded all my old email from the yahoo server even though they were already imported with the pst file. I had a duplicate of every email.
Why is this happening? Any ideas on how to quickly erase all the duplicate emails or how to stop this from ahppening in the first place?
