B2C Custom SMTP Email Provider
Emails for email verification and password resets are from Microsoft (firstname.lastname@example.org) on behalf of the organization. Allow emails to be sent from the organization’s email domain. Whether this is through SendGrid or by any other means. We use Office 365, at least allow this scenario to work as I’m already logged into Azure to configure all this with my Office 365 account.
