I am back up. Periodically tried to log in, kept getting the usual errors, and then about 2PM EST - bingo, right in. I did send an email to the Senior Tech who had been very helpful last week. Never heard back, but I sent him a link to this forum and asked if he thought AT&T was phasing out XpressMail.

I have no idea if going back up is related to the email or just coincidence. Let's see how long it lasts. In the middle of negotiating a major deal and our Executive Director is not happy he can't get me via email reliably on a moment's notice. Probably going to force me into a Blackberry on Monday.
