i am getting the following error in windows live mail while checking my hotmail account

Unable to send or receive messages for the Hotmail (ramizbaig) account.

Server Error: 0x80072EFD
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80072EFD

i would like to state that additionally window live mail is used to check a gmail account, a gapps account and a imap account all 3 of those are working fine.

also i am able to use web browsing perfectly on chrome but internet explorer is giving me a connection error? maybe thats whats causing hotmail to misbehave as well.

looking forward to the resolution of my problem.

regards
