I have the same issue. As time goes on the pop ups appear more frequently-almost immediately after OKing the window to close it. Now i just drag the window off the screen and leave it. Most of the time the email still works, but other times I have to close outlook 2010 and reopen it. Other times i go into account settings and use the "repair" option which typically works. On occasion I find my saved password has changed by itself and I have to change it back. Still seems to be some kind of weird Cox problem. If you get the right person at Cox for technical assistance they will acknowledge that, but typically you talk with someone who says they don't know about any Cox problems.
