Has anyone had success using Office 365 for SMTP with Looker?
I get this error when attempting to send a test email:
Failed to send mail: 504 5.7.4 Unrecognized authentication type
I’m selected the check box for SSL/TLS. I did note that the setting I’ve had to use with another tool is START TLS. I’m not clear on whether that variant should be handled by the SSL/TLS option.

Starting in Looker 7.20 out later this month, Looker will support the PLAIN SMTP authentication protocol, which means that the recommended authentication config for Office365 will now work when setting up office365 as your custom SMTP server.
The caveats Ani mentioned above still apply for MFA and the Microsoft Security Defaults.
