I looked at ATT's help site and saw directions for setting up OE to work with an ATT account:http://forums.att.com/t5/Email/Setting- ... -p/2013425
This should be independent of whether you use Hotmail or not. Outlook Express is known as a mail client and you can have it set up to receive mail from various online e-mail accounts, including ATT. Give it a try using their directions. If you have any other questions about specifics for OE and ATT you might best talk to ATT's customer service.
