Outlook e-mail not downloading

I'm having the opposite issue of sending where I can't log into my e-mail account from Outlook.  Yesterday, I had checked my e-mail before going to work.  Last night - different story.  Started laptop and got the 'need password'.  That shouldn't have happened, but I continually got rejected for bad userid / password.  I even changed my password twice, but still had the same issue.  After three calls to tier I, two fumbled passes to tier II, and an hour and a half of my life went by, no change.  Same tonight, I still can't login.  Anyone else having this type of issue and why can't Cox fix this issue.  The other frustrating part is my wife's e-mail downloads just fine, so what is specific about my account all of a sudden.
