Yahoo and AT&T have recently changed how they allow Authentication.

  • Select 'Menu app icon' > 'Options/Preferences'
  • In 'Options/Preferences' left Pane select Privacy & Security
  • Select checkbox 'Accept cookies from sites'

You are probably already using these server settings, but you may not have changed the 'Authentication Method'.

Server Settings: IMAP Incoming server name: imap.mail.att.net Port : 993 Connection Security: SSL/TLS Authentication Method: OAuth2 User Name - Enter your full email address.

SMTP Outgoing server name: smtp.mail.att.net Port :465 using Connection Security: SSL/TLS Authentication Method: OAuth2 User Name - Enter your full email address.

then restart Thunderbird. Yahoo will prompt you to logon to allow thunderbird access. then a token is created and stored in thunderbird which it will use from then onwards.
