A client of mine has used Outlook 2007 for years. All of the sudden emails from years ago are downloading themselves and she is getting duplicates and ones that she already deleted. When I looked on her account in Outlook.com I found a fold under "Deleted" call POP. It has emails from 2011 and has over 16,600 emails in it. I think this may be the problem. Hard to find info on line about it. It sounds as if it is a Outlook safeguard but I think if may be causing problems. Can I simply delete it?
