As far as I can tell I have Outlook setup to delete emails on the server after I download them to my PC. However, a few weeks ago Outlook suddenly started downloading multiple copies of the same email. I can't figure out what the common factor is between the ones that are downloaded once nor the ones that are downloaded multiple times - sometimes 2 copies, sometimes 3. Sometimes on the same download, sometimes hours apart.
Weird! All suggestions most welcome. Maybe among the obvious and not so obvious there will be something I have missed!
