I've been able to send and receive email messages without problems since I started using Windows Live Mail over a year ago.  However, when trying to send one message a couple days ago, the send message task failed and I received an error message saying it was unable to send this one specific email message because "the setting for your outgoing email [SMTP] server might need to be configured."  "Windows Live Mail Error ID: 0x800CCC79".   No changes have been made to any of my previous settings, including server authentication.  I'm able to send & receive all other messages.  This message errors out every time I send/receive mail.  How can I remove this error message and/or stop trying to send this email message when I send/receive messages?
