On two computers, I have an annoying popup. A number of times each day, on both computers, a popup will ask for the password for a particular email address. It is usually an att address, but sometimes other addresses. I have called AT&T support, but all they will do is confirm that emails to my AT&T addresses appear in my AT&T webmail. After confirming, they conclude that this is not an AT&T problem, but an Outlook problem. I think they are right. Of course, Microsoft is no help. I use Outlook 2007. Any observation would be appreciated.
