Step 4: Replicate Active Directory data to the Edge Transport server

Learn how, when and what information gets replicated from Active Directory to an Edge Transport server via the ADAM partition and how to force a manual EdgeSync synchronization.

The Edge Transport server does not receive a complete copy of Active Directory for security reasons, but there...

is still quite a bit of information that gets replicated, including:

  • The safe senders list
  • The Remote Domains list
  • The Accepted Domains list
  • Recipient data including email address, contacts, distribution lists, etc.

After the initial replication completes, it is up to Exchange Server to keep the information in the ADAM partition up to date. Remember that the Edge Transport server is not a domain controller. This means that the ADAM partition is not updated through the normal Active Directory replication process.

Instead, Exchange Server keeps the ADAM partition synchronized with Active Directory. The EdgeSync synchronization does not occur nearly as quickly as true Active Directory replication though. Exchange Server synchronizes changes to configuration-related data hourly; it synchronizes changes to recipient data once every four hours.

Of course, there may be situations in which waiting four hours for a directory synchronization to occur is simply impractical. Fortunately, there is a way to force a manual EdgeSync synchronization. Just open the Exchange Management Shell and enter this command:

Start-EdgeSynchronization

Now that you have created an Edge Subscription, you must wait for the initial synchronization to complete. The amount of time it will take varies depending on the size of your Active Directory and the size of your Exchange Server organization. If possible, recommend just letting the synchronization run overnight.
