Mailbox Server role

The Mailbox Server role is installed in the Active Directory site where at least one writeable domain controller is deployed which is also a global catalog server.

What is Global Catalog Server?

The global catalog is a feature of Active Directory domain controllers that allows for a domain controller to provide information on any object in the forest, regardless of whether the object is a member of the domain controller’s domain.

Mailbox server includes three major components as listed below.

Unified messaging (UM) functionality which existed in previous versions of Exchange Server has been deprecated in this release. Since UM functionality no longer available, Customers can choose to transition to Skype for Business Cloud Voice Mail as alternative,.

Edge Transport role

Edge transport role is designed to run in perimeter network that reduces the surface attack area. The Edge Transport role is an optional Exchange Server role as we can also use the Exchange Online Protection (EOP) as cloud based filtering service or any third party validated filtering solution as an alternative to it. When deployed, Edge transport role handles all external mail flow for the Exchange organisation and provides anti-spam protection for Exchange organisation.
