I have been unable to send emails with SMTP for the last couple of days, although it previously worked without problems.
System: macOS 10.14
SMTP Settings: Server: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2 Username: full email address
When sending an email, I get a "Login to account XXX failed. Login to server smtp.office365.com with username YYY failed".
Things I have already tried: (1) if I try to send email directly from Outlook, it works. (2) removing the SMTP server in TB and adding it again didn't work. (3) removing saved passwords in TB: if I go to Preferences -> Privacy -> Saved passwords, there is one line only:
Removing that line and restarting TB will result in a popup taking me to institutional login, where I enter my email and pwd. I login without problems, but I still get the same error.
IMAP is working fine, so I am a bit unsure what the issue might be. I am not sure if SMTP passwords are stored somewhere else and that is creating problems, or if my prefs.js file is somehow corrupted (nothing obvious I could tell by reading it).
Any help is greatly appreciated, thanks in advance.
