Creating an Exchange DAG Client

Before you use the Exchange Database application in Database Availability Group (DAG) environments, you must configure a DAG client and select the appropriate server. The DAG client stores the configuration information for all of the member servers, and coordinates backup and restore operations for different servers. The DAG client is also referred to as a pseudo client or a master client.

Before You Begin

You must install the Exchange agent on each member server using the fully qualified domain name.


  1. From the navigation pane, click Solutions > Apps > Exchange.

    The Exchange servers page appears.

  2. Click Add, and then click Add Database.

    The Add Exchange Database dialog box appears.

  3. In the Server name box, type a name for the new DAG client that you are creating.
  4. From the Plan list, select a plan
  5. From the AD domain name list, select an Active Directory domain name.

    Note: Only configured Active Directory domain names appear in this list. You can add a new domain name to this list. For more information, see Adding Domains.

  6. Type the user name and the password for the selected domain.
  7. Optional: If DAG is set up in a restricted environment, install the application on a proxy computer that has access to both the CommServe and the Active Directory. Select the Access node for DAG discovery check box, and then select the appropriate proxy computer.
  8. Click Discover.
  9. From the DAG servers list, select a DAG server that has an available member server.
  10. From the Member servers list, select a member server, and then click OK.

    You can later add more member servers to a DAG server. For more information, see Adding a New Exchange DAG Member Server.

  11. Click Save.


A new Exchange DAG client containing a default subclient is created.

What to Do Next

You should now assign content to the default subclient. For more information, see Assigning Content to Default Subclient.
