Hey techbeck,

if you're using STARTTLS, there could be an issue with the certificate chain; you might need to import the Office 365 certificate and chain into FortiAuthenticator manually.

This KB is for Gmail, but the certificate and STARTTLS configuration would still apply to Office 365:

Hope that helps!
