Is it possible that MS Graph List User API returns users with empty or null userPrincipalName? And what would be the cases if so?

    Hi @Scott Jiang

    No!

    This property is required when you create a user, and it does not return a null value.

    userPrincipalName is required property for user.

    We have tried to create user without userPrincipalName but its showing error.
