What built-in tool do you have to allow you to manage Exchange store recoveries?
Exmerge / Recovery storage group

What is Isinteg?

Where does Edge role store its settings?

The Edge Transport server uses Active Directory Application Mode (ADAM) to store the required Active Directory data, which is data such as Accepted Domains, Recipients, Safe Senders, Send Connectors and a Hub Transport server list.

What's Edge synchronization?

The process that the Microsoft Exchange EdgeSync service performs to propagate data from Active Directory to the subscribed Edge Transport server. Configuration data is synchronized one time each hour. Recipient data is synchronized one time every four hours.

 You can use the Start-EdgeSynchronization cmdlet in the Exchange Management Shell to start immediate synchronization.

How do you enable Edge subscription?

Open the Exchange Management Shell on the Edge Transport server, and enter this command:
New-EdgeSubscription –file "C:\subscription.xml"
Answer “Y”
Transfer EdgeSubscription.xml to the Hub Transport server
Open Exchange Management Console
In the left tree choose “Organization Configuration” and then “Hub Transport”
In the Actions pane click “New Edge Subscription”
Choose active directory site, if you have multiple sites though, then you should make the Edge Transport server a member of the site that has the fastest (or most reliable) network connectivity to the perimeter network.
Use the Browse button to browse for and select the subscription.xml file.
Verify that the Automatically Create A Send Connector for this Edge Subscription checkbox is selected, then click the New button to import the XML file and create the Edge Subscription.

What's the default replication interval for Edge sync?
By default, configuration data is synchronized to AD LDS once every hour , and recipient data is synchronized to AD LDS once every four hours . You can change these intervals using the Set-EdgeSyncService cmdlet.

What's Edge subscription?

The Edge Subscription is the record of an Edge Transport server that has been subscribed to an Exchange organization. The ADAM directory service on a subscribed Edge Transport server is updated with information from Active Directory by the Microsoft Exchange EdgeSync service.
