As a result, any of the following objects that were created manually will be deleted: accepted domains, message classifications, remote domains, and Send connectors. After creating the Edge Subscription, you must manage these objects from inside the organization and allow EdgeSync to update the Edge Transport server. Also, the InternalSMTPServers list of the TransportConfig object will be overwritten during the synchronization process. EdgeSync requires that this Edge Transport server is able to resolve the FQDN of the Mailbox servers in the Active Directory site to which the Edge Transport server is being subscribed, and those Mailbox servers be able to resolve the FQDN of this Edge Transport server.
