Sending of the message failed. An error occurred while sending mail. The mail server responded: <work@email address>: Sender address rejected: not owned by user personal@email address. Please verify that your email address is correct in your account settings and try again.

This message suddenly coming up after a Thunderbird update, and I cannot send messages from my work email because I don't "own" it. How do I fix this?

TIA.

Thanks. Solved it anyway eventually. The outgoing server had been reset as a different smtp address for some reason in one of the Thunderbird updates, so kind of a variation on your answer.

Some possibilities: - if you aren't using secure settings, your server may not be recognizing you. - if your sending email id doesn't match the SMTP server email id, that would also cause refusal.
