The Exchange Server 2010 Edge Transport Server is not part of the internal

Active Directory and Exchange organization, and is typically installed in the network’s

DMZ. A mechanism obviously needs to be in place for keeping the server up to date with

information.

For example, for the recipient filtering in the Edge Transport Server to take place, the server

needs to know which recipients exist in the internal Exchange environment. The Edge

Transport Server also needs to have knowledge about the existing Hub Transport Server in

the internal Exchange organization, where the Edge Transport Server has to deliver its SMTP

messages to.

This information is pushed from an internal Hub Transport Server to the Edge Transport

Server by a process called “Edgesync”. Please note that for a successful synchronization from

the Hub Transport Server to the Edge Transport Server, you have to open port 50636 on the

internal firewall. This port has to be opened from the internal network to the DMZ and not

vice versa.

To setup an Edge Synchronization, a special XML file has to be created on the Edge Transport

Server. This XML fi le has to be imported to a Hub Transport Server on the internal network

creating a relationship between the Edge Transport Server and the respective Hub Transport

Server. Once that relationship is created, the Edgesync service can be started. To setup the

Edgesync service, please follow these steps:

1. Logon to the Edge Transport Server using an administrator account and open an

Exchange Management Shell;

2. Enter the following command:

New-EdgeSubscription –Filename <<filename.xml>>

Copy the <<filename.xml>> to a directory on the Hub Transport Server.

3. Logon to the Hub Transport Server using an administrator account and open an

Exchange Management Shell command prompt.

4. Enter the following command:

New-EdgeSubscription –Filename <<filename.xml>> -CreateInternetSe

ndConnector:$TRUE –Site “Default-First-Site-Name”

When successfully finished on the Exchange Management Shell command prompt, enter the

following command:

Start-EdgeSynchronization

The Edge Synchronization process should now successfully start.

5. On the Edge Transport Server, open the Exchange Management Shell and check if the

settings are identical to the settings on the Hub Transport Server.

When making changes to the internal Exchange organization, these changes will

automatically replicate to the Edge Transport Server in the DMZ.
