I've checked that server settings are STARTTLS and updated TB to the latest version, also restarted the computer. I still get the same message An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. Please verify that your email address is correct in your account settings and try again.

Chosen solution

You're showing us the Write window. Try again in the main Thunderbird window.

Maybe you checked the incoming (POP/IMAP) settings and not the outgoing (SMTP) settings?

Zenos, you are correct Maybe you checked the incoming (POP/IMAP) settings and not the outgoing (SMTP) settings? Problem solved, thank you
