When I log in I get this message;

Unable to send or receive messages for the Live.co (xxxxxxx.xxxxxxx) account.

Server Error: 5102
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE20003

Can someone please advise what is happening and how can I fix this?

Many thanks,

Richard.
