I have Office for Mac 2011, Outlook 14.6.0, OS X 10.6.8.

I'm getting the following error message: "Outbound mail refused - 45.48.161.49" - it directs me to a TWC address and has what I think is an error message number: R0209002. I called TWC and they checked my servers and ports and all is fine. I can receive mail in Outlook, and I was able to send test emails in webmail. But Outlook is refusing. I restarted Outlook and then my computer to no avail.

As a side note that may or may not be related: Outlook has dredged up an ancient former email account that I haven't had for years and isn't in my Accounts and is giving me error messages saying that address is invalid. Well, I know that - it's not my account anymore. So why is it doing that? But I don't think it has anything to do with refusing to send mail.

Anybody have any clues here? Many thanks, as always.
