Original title: Windows Live Mail stopped syncing with Outlook.com

For the past several days, my Windows Live Mail running on Windows 7 stopped syncing and has not been able to connect.  I get the following error message:

Unable to send or receive messages for the Outlook (tamdwong) account.

Server Error: 4102
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00001

The only thing that may have changed was that I was re-organizing mail between accounts and also deleted an old email account that I was not using anymore.  However, it only seems to affect the Outlook.com account.

I also ran the windows essential repair from the control panel and a diagnostic said that it could not connect. 

Thanks for your help.
