Can't send emails but I can receive them with TB

I can't send emails and I get this message -

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I have checked the outgoing settings for password and it says normal password. This problem started when I changed my BT email password

If you told Thunderbird to remember your account password, try to delete the old password. At the top right of the Thunderbird window, click the menu button ≡ > Settings > Privacy & Security > Passwords > Saved Passwords

Select the SMTP password for your BT account - Remove. Thunderbird should then prompt you for the new password the next time you attempt to send a message.

Excellent christ1 I followed your instructions and found an old saved password listed below my new password. When I deleted it, I could now send emails. Well done you.
