Configure database availability group network properties in Exchange Server
Configurable properties include the name of the DAG network, a description field for the DAG network, a list of subnets that are used by the DAG network, and whether the DAG network is enabled for replication.

You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Database availability groups" entry in the High availability and site resilience permissions topic.
You can configure a DAG network only when automatic network configuration has been disabled for a DAG. For detailed steps about how to disable automatic network configuration for a DAG, see Configure database availability group properties.
For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.
Use the EAC to configure database availability group network properties
In the EAC, go to Servers > Database Availability Groups.
Select the DAG you want to configure, and in the Details pane, under the DAG network you want to configure, choose from the following configuration options.
These options will only be visible if you have selected Configure database availability group networks manually on the DAG properties page.
Disable Replication or Enable Replication: Configures the replication settings for the DAG network.
Remove: Removes a DAG network. Before you can remove a DAG network, you must first remove all associated subnets from the DAG network.
View details: Configures DAG network properties, such as the name, description, and associated subnets for the DAG network. You can also view the network interfaces associated with those subnets, and enable or disable replication for the DAG network.
Use the Exchange Management Shell to configure database availability group network properties
This example adds a subnet of 10.0.0.0 and subnet mask of 255.0.0.0 to the DAG network MapiDagNetwork in the DAG DAG1.
Set-DatabaseAvailabilityGroupNetwork -Subnets 10.0.0.0/8 -Identity DAG1\MapiDagNetwork
How do you know this worked?
To verify that you've successfully configured the DAG network, do the following:
In the Exchange Management Shell, run the following command to display DAG network configuration settings and verify the DAG network was configured successfully.
Get-DatabaseAvailabilityGroupNetwork <DAGNetworkName> | Format-List
