Thunderbird for Android v13 says the outgoing SMTP server settings are OK, but attempts to send mail fail with "Mailbox unavailable". The outgoing server settings match my desktop TB email settings, but notably there is no place to enter the password. Right now, I suspect the problem has something to do with the OAuth2 authentication which is an opaque hidden password layer that was also problematic on my desktop.
My email provider is Rogers/Yahoo. Does anyone have settings that work?
