POP3 server won't let me log in
I've been using Outlook to read my email for over 20 years and it mysteriously stopped working on August 4th, 2022. I've reset the Secure Mail Key several times, but simply cannot log in to the POP3 server. Webmail works fine. Everyone at AT&T wants to tell me how to set up Outlook or to simply keep trying to change the password until it magically works. What's the real answer?
