I am trying to set up MFA on a small Microsoft 365 tenant. I have enabled Security Defaults Azure Active Directory Properties per the Microsoft document 

"Set up multi-factor authentication". Now the user cannot log into desktop application Outlook In Microsoft 365. Modern Authentication is turn on and legacy per user MFA is off. What am I missing?
