Windows Live Mail is the e-mail client that is part of Microsoft’s Windows Live suite of applications. A common error encountered when using Live Mail has to do with authenticating a server for outgoing mail. Learn how to fix Windows Live Mail Error 0x800CCC0B.

Authentication of Outgoing E-mail Servers

When receiving mail in any e-mail client, it is necessary to use a username and password to authenticate that you have the right to receive the e-mails in your account. The Post Office Protocol (POP) server, managed by your e-mail provider, handles incoming mail.

    Many e-mail service providers, however, do not require authentication for outgoing mail. Most e-mail service providers use the Simple Mail Transfer Protocol (SMTP) to handle outgoing mail.

    If you receive Windows Live Mail error 0x800CCC0B, it is possible that your e-mail service provider requires authentication for outgoing as well as incoming mail.

    In Windows Live Mail, you can turn on authentication on an account-by-account basis. Before you proceed with the fix below, be sure you are applying it only to the account(s) that are experiencing the error. Adding authentication to an account that does not require it can cause further errors with the account.
