Overview

Approval emails are sent from outside of the organization boundary and routed to the email domain of the specified recipient. Which is to ensure that all organizational policies for inbound mail are respected.

For customers whose MX record points at another filtering service (for instance, Proofpoint or Mimecast), messages will be routed to those services first per MX routing priorities, and not directly to Office 365 or on-premises mailboxes.
