The solution for this particular error code can be found in a Microsoft solution article that was shared by Beebeesa. Take a look at this link here for more information.
Also, I would just like to make sure that your Windows Live mail configurations are using the most updated mail server settings. Give these settings a try and see if it helps resolves the issue.

SMTP Server (all domains): outbound.att.net

Incoming mail server: POP3
Outgoing mail server: Outgoing server (SMTP) requires authentication
Incoming mail port #: 995, secure connection (SSL) checked
