Outlook can't login to my sbcglobal.net account
On 6/8/21 Outlook on my PC stop updating email. The error said login was rejected. I get a window on my screen from outlook telling me to enter the email password which I did, nothing changed. As I investigated I found out I had Outlook 10 which Microsoft stopped supporting last year. So I upgraded to Microsoft 365 with latest Outlook Release it loaded fine but I have the same problem, it fails login. I have verified my settings with at&t website, I am using POP3. I have changed my password 3times, removed all Unicode Characters. I can go to the AT&T Currently website and login just fine. My iphone can login and retrieve email just fine.
I was told by AT&T support 2 years ago I didn't need to create a secure email key and again in the last few days when I talked with AT&T support
I didn't do anything to my PC on 6/8/21 that would have changed anything.
