Others have this problem but I haven’t seen a solution. Problem occurred for the first time today (08/20/25). I opened thunderbird on my Windows 10 PC. All updates and thunderbird are current. I can create and send emails fine, but I can not download new mail. I can see 20 new emails on my phone but can not download to my PC. I called AT&T support. My email is sbcglobal domain. They tried to help. Went into server settings and the AUTHORIZATION TYPE was OATH2. There were 4 other options. I tried them all. (Normal PW, Encrypted PW and 2 others). Nothing worked. And now, OATH2 is not one of the available options. No idea how it was originally set. AT&T said that was a Microsoft Authorization type, so I contacted MS support (chat). They were no help. They immediately said “Thunderbird is a 3rd party client, we don’t support it”. I told him it might have been the most recent Windows update that caused the problem. He said “Contact Mozilla”.

Any help would be appreciated. Another question I have is, if I were to delete the Thunderbird application and re-download it. Would I lose all my emails and folders? That would be life-changing in a bad, bad way.

First, do not reinstall as that often causes more problems. Try these three links, as they usually have the solutions for AT&T

Thanks David. I followed the first link. Created a Secure Mail Key. Changed the AUTH TYPE to regular password, tried to open mail, got a pop-up asking me for a new password, pasted the Mail Key, wham bam thank you ma’am. Here came my mail.

Conclusion, non OATH2 mail clients (like Thunderbird) require a secure mail key IN PLACE OF your existing password.

You're welcome. Actually, the use of OAUTH2 varies by email provider. Gmail uses it with an app password, and Outlook does with normal password. Go figure. :)
