Vista - 0x800CCC92 Error in Outlook 2003

I recently bought a new Dell system with Vista Home Premium. After I installed Office 2003 from my previous system and ran Outlook, I got the above error message claiming my password could not be authenticated. I can send mail, but I can't receive it.

I have tried everything: I switched to Windows Mail and got the same result. Ditto for Thunderbird and Live Mail. I have also gone to the command prompt as an administrator and fiddled with the "netsh autotuning" command I have seen posted on the Internet. Nothing has worked. Anyone have any ideas/solutions?

I'm not a big pro, but it sure sounds like you put in the wrong password, and it's your provider not allowing you and not the computer

Thanks for your response, Shmookay,

Since posting I was able to solve the problem, which entailed leaving off the @-and-beyond portion of my username. I hope that's helpful to other people who encounter the same problem.

Again, thanks for your help.
