My OS is windows 7 and I use Outlook 2007. For no reason and from nowhere I seem to receive all the old messages that I had read and deleted, from Nov 2010 - about more than 2,000!. I have msn email and use Verizon DSL. I have not added or edited any of the configured email accounts which are msn and verizon. Hope someone can please tell me what I am doing wrong. Thank u.
