I'm able to receive messages in Thunderbird from my hotmail account but am unable to send them. This problem started the version before 115.4.3. This use to work. I have not changed any settings. I've tried removing the account and re-adding, but that didn't fix the issue.

The error message is: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Attached are images of the servers settings I have.

Help!

Chosen solution

The authentication method for incoming and outgoing should be OAuth2. Remove the entries for the account from Saved Passwords in Settings/Privacy & Security, accept cookies in the same section, restart TB, enter the account password in the OAuth window to allow TB access.
