Since yesterday, I have been unable to send or receive mail from one of the hotmail accounts (all accounts managed within Windows Live Mail).

The message I keep getting when I try to retrieve is:

Unable to send or receive messages for the Hotmail (debra.fett) account.

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

Any help would be great, as this is a very active account.

Thank you,

Debra
