One hotmail/live account stopped working this morning. Been trying to regain access but unable. My account on Hotmail is functioning without problem, the one my wife uses gives the following error message: 

Unable to send or receive messages for the Hotmail (name of user) account. To send and receive messages in your Hotmail account, go to http://hotmail.live.com on the Web, or try again later. To get help from Windows Live Customer Support, go to http://support.live.com and click Windows Live Mail in the list of services.

Server Error: 0x80072EFF

Server: 'http://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'

Windows Live Mail Error ID: 0x80072EFF

No indication of a problem I can find in the support areas.

I tried to access her account on my computer where my Hotmail account works but I receive the same error as with her system. Problem is not computer related.
