Cannot add bellsouth.net e-mail account to MS Office 365/Outlook
Got new HP lap top computer - running Windows 11 Home.
Cannot set up ATT (bellsouth.net) e-mail account. No problem with g-mail account.
Followed ATT instructions for manual set up tried POP/IMAP settings with 16 digit secure mail key. Gets as far as the inbound server login screen and does not finish.
