Hello!
 I get the following error message when clicking on Windows Live Mail 2011:

Unable to send or receive messages for the Windows Live Mail account.
Server Error: 0x80048849
Server: 'http://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80048849

I am running Windows 7. 
When I have new mail, the program works fine and there are no error messages.... however, it displays
the above message every other time I open the Windows Live Mail 2011 program.

I have tried repairing the Windows Live 2011 programs using control panel, and have re-installed Windows Live 2011
and the same problem occurs.
I have removed and re-installed my mail account several times and that does not help, either.

My Hotmail address is:  <removed by the moderator>

Please help!  Thank you!
