I was in Windows Mail when suddenly a box popped up asking for my username
and password from Windows Mail.. Although I attempted correctly several times
it still will not work. I contacted my kerrlake server and we tried several
things including deleting the account and resetting it back up but it still
will not open. I can receive my emails on my blackberry and can get on the
internet. Also, a protocal error message pops up. Please help!

I have gone through this several times and the best thing to do is NOTHING. When you fist see that window (next time), close it off! Don't enter information or click ANYTHING except the "X" at the top right corner of that small window.
Once you enter information, Windows Mail sees it as a NEW entry and it will fail as well. But this time the information is sent in to your ISP.
Close the window with the "X" and 'send/receive' again.
I first re-entered my username and password and that's where trouble began! I talked to every AT&T agent in New Delhi and finally had to reset my password.
Close the small error window and try again. If that fails, close Windows Mail and open it again.
I know this is not "technical", but it's the only thing I've found to save the headache of password reset.
