Windows Live Mail not synchronising with Outlook.com since 1am on 4-Oct.  Before this it was working fine.  Nothing has changed on my system - so I assume it’s a Microsoft server problem.  Any comments?

The message I get is:

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

Server Error: 5102

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

Windows Live Mail Error ID: 0x8DE00002

I can access the account via a browser. I am using Windows 7.
