Since this morning i'm not able to send or receive mail on my PC from the hotmail account that I've had for years for my business. I get the following error: 

Server Error: 0x80072EFE
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80072EFE

Please help
