When I set up an account (Outlook or Gmail) to use OAuth, sending emails fails. When I click 'send,' a large window flashes up, but then nothing happens until I receive a server time-out error.

When using OAuth for retrieving emails, no errors occur.

If I switch to an app password, then it works fine.

  • Using Thunderbird version 115.2.2.

You did not repond to the requested info so I'm not sure what server name you were using.

TRy using Authentication Method: OAuth2 and change the SMTP server name from the default smtp.office365.com to smtp.outlook.office365.com

Please note you will need to access webmail and switch off the 2FA and use normal password not app generated password.
