Managing personal Outlook.com account settings, security, and privacy
This worked for me -no problems for several months-
Open control panel - click on Internet Options - go to Security tab and click on it.Go to trusted sites. You will see a box that say SITES- a list of trusted sites will appear - delete any site that refers to email - outlook - email - live - etc. - go to you email. You should be all set. If not try try to login in to Windows Live 2012. Your emails also appear here. Hope this helps
