I have been getting this error message for the last two days trying to access my live email account:

Unable to send or receive messages for the Live (Removed PII) account.

Server Error: 5102
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00002
