Exchange Server 2007 : Establish EdgeSync Subscriptions

Problem : Exchange servers, from a working perspective, should not be directly connected to the Internet. There is important information involved in addition to a connection to Active Directory, which should be protected. You might protect your servers by establishing firewalls and other hardware-based solutions; however, another form of protection to consider is that of the Edge Transport server. After you have the server up and running, how do you link it to your back-end, internal Exchange organization?

Solution : EdgeSync Subscriptions allow you to connect your Edge Transport and Hub Transport servers together. To create an EdgeSync Subscription, you have to begin the process on the Edge Transport server. Perform the following:

1.	Open the Exchange Management Shell (EMS).
2.	Type New-EdgeSubscription -FireName “c:\EdgeSubscriptionInfo.xml” and press Enter. (Note that you can call the file whatever you like. This is just an easy-to-remember example.)
3.	You will be asked to confirm the process. Type Y and press Enter.
4.	Now, take the file that was created and move it (with a thumb drive or through some other valid means) over to the Hub Transport server.

On the Hub Transport server, perform the following to complete the EdgeSync Subscription process:

1.	Open the EMC.
2.	From the Navigation Tree, expand the Server Configuration work center and click Hub Transport.
3.	Select the Edge Subscriptions tab.
4.	From the Actions pane, select New Edge Subscription to open the wizard.
5.	On the New Edge Subscription screen, shown in Figure 1, Provide the Active Directory Site toward which you want this subscription to apply. You also have to Browse to the location of the .xml file that was created from the Edge Transport server. After you have the options selected, click New. Figure 1. Establishing the Edge Subscription on the Hub Transport server.
6.	After the EdgeSync Subscription is complete, click Finish.

PS Note

You can use the Test-EdgeSynchronization cmdlet in the EMS to confirm that Active Directory and ADAM are synchronized, as well as to confirm the synchronization status of a single recipient.
