Upgraded to Thunderbird 140 and AT&T email not syncing

sfhowes risposto
Butch Henderson

I upgraded to Thunderbird 140.0.1esr (64 bit) and 1 of the 4 email accounts has stopped syncing.

The one that stopped syncing is AT&T / Yahoo email via imap inbound and smtp outbound. It was working on the 128 release but as soon as I updated it stopped syncing.

I can still get email to/from the other 3 accounts, it still works on my phone and on my laptop with Thunderbird 128.12.0esr (32-bit) it is still working OK.

I have double checked account info and passwords and no issues that I can see.

My next thought is to downgrade back to 128 unless someone knows of a fix.

Have you tried removing the entries for the account from Saved Passwords in Settings, restarting TB, and entering a new secure mail key generated on the AT&T site, when asked for a password?

Thank you for the link I'll let them know I am seeing the same problem.

I have not tried your / their suggestion of removing the entries for the account from Saved Passwords in Settings, restarting TB, and entering a new secure mail key generated on the AT&T site, when asked for a password since that would break the other 2 working email clients.

All settings are correct according to the other link and I had also compared to what I have on the laptop.

The phone's mail app probably accepts the regular account password, and it's my understanding a secure mail key is for desktop mail apps, and a separate key is required for each desktop app, or for each computer that has the same account. So, using a new key for TB on a desktop shouldn't affect the account on the laptop.
