I changed my BT email password but cannot send emails from Thunderbird. I can receive them. I receive this message - 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 my outgoing server settings which are -

Description: BT Yahoo Server Name: mail.btinternet.com Port: 465 User Name: rvynerp@btinternet.com Authentication method: Normal password Connection Security: SSL/TLS

My BT email works fine for both receiving and sending so the problem is with Thunderbird outgoing mail settings

Do you only have one BT mail account in Thunderbird?

Have you updated/checked the stored password in Thunderbird for both incoming and outgoing?

  • Settings > Privacy & Security
  • Scroll to Passwords section
  • click on 'Saved Passwords'
  • click on 'Show Passwords'
  • Locate the outgoing smtp://bt account line for account where 'username' is the correct email address.
  • Is the passwords correct?
  • Right click on the smtp:// line and select 'Edit Password'
  • Completely clear all contents and then carefully type in the correct password.
  • Click on 'Close'

Exit Thunderbird and wait a few moments for background processes to complete - then restart Thunderbird. Wait for Thunderbird to perform the initial check with server to download new mail. Then test sending.
