Thunderbird lost the ability to send email
I'm running Thunderbird 45.7.0 on a Windows 10 PC. It was working fine until this morning when Thunderbird stopped sending emails. I can still receive them. When I try to send, I get a dialog that says "login to server outbound.att.net failed". Then I can re-enter the password but it still doesn't work. I can access my email on the att.net webpage and my cell phone so the password is correct. I made no changes to the account settings in Thunderbird so they are correct. I called AT&T help and they said it's not their problem since I can get the email via the webpage. I've occasionally seen this behavior before but it only lasts a few minutes. I've been unable to send email all day. I have rebooted.
Thanks,
Brian

Other people are having problems with AT&T e-mail servers today also.
To determine if the problem is with Thunderbird or the e-mail server, Create a new profile in Thunderbird for testing
If you still have problems with e-mail when using the test profile, then the problem is with the e-mail servers, not Thunderbird.
If the test profile works, then the problem is either a glitch in your e-mail account in your main profile, or a glitch in your main profile.
Go back to your main profile and Create a new "account" in Thunderbird for the same e-mail address, to test to see if it works better than the old account.
If you are using POP, then first move all your e-mails from the faulty account to Thunderbird's "Local Folders", then remove the faulty account before creating the new account. This will be necessary if you create the new account using POP also.
For IMAP:
1. Thunderbird menu: Tools: Account Settings. (If you cannot see the Thunderbird menu, press the Alt key or F10 key on your keyboard to show the menu)
2. Click the "Account Actions" button on the bottom left and choose, "Add Mail Account".
3. Enter your name, e-mail address, and password, then press the "Continue" button.
4. Continue with the setup until the correct settings are obtained.
5. Thunderbird may complain that you already have an account with the same name, and will prompt you to enter a different name for the account you just created.
If the new account works properly, then use it from now on.
Before removing the old account (Thunderbird menu: Tools: Account Settings: Account Actions: Remove Account), make sure that your e-mails are the same, or moved from the old faulty account to the new one.

If the new "account" in Thunderbird doesn't work, but the account in the test Profile works, then switch to using the new Profile and import your stuff from the old profile to the new profile.
Thanks for your quick reply Bruce. I created the new profile and the behavior is the same - receive but not send. So I guess I wait until AT&T sorts this out.
Since I had the same behavior, I went back into profile manager and clicked on default and ticked the box for use this profile at startup. My inbox is now back as it was.
