Instance Property
The email claim is present by default for guest accounts that have an email address. Your app can request the email claim for managed users (those from the same tenant as the resource) using the email optional claim. On the v2.0 endpoint, your app can also request the email OpenID Connect scope - you don’t need to request both the optional claim and the scope to get the claim. The email claim only supports addressable mail from the user’s profile information.
