Using Outlook email program from Microsoft Office suite 2010. The evening of Oct 20, 2013 all email messages vanished from my inbox.There are no established "rules" that I know of.
I have three email accounts through comcast.net. Phenomenon only occurs on one of the three accounts: the "main" one which is configured to receive all updates from microsoft and eset. Messages linger for a few hours and then evaporate.
Via research within Microsoft Outlook forum, came a suggestion that my anti-virus program could be responsible.
(Apparently McAfee and Norton eat emails from time to time.)
Problem began while I was using Win 8.0. Continues to plague my system into Win 8.1. I "repaired" Outlook 2010. Nothing I've tried thus far corrected the problem.
Please help. Thank you.
