Knowledge Base FAQ Item #7500034
Q7500034: I want to use our Offcie365 account to send out e-mail alerts. However, we do not want to use OAuth2 as it is very complex to configure. Is there a way to use password authentication with Office365?
Yes, it is possible. Use smtp-legacy.office365.com on port 587 using STARTTLS.
Please note that the default security will not allow you to, and you'll end up with an error from the smtp-legacy.office365.com server saying:
535: 5.7.139 Authentication unsuccessful, user is locked by your organization's security defaults policy
