Can I undelete a mailbox-enabled user?

Yes, you can undelete mailbox-enabled users with the online restore function of Recovery Manager for Active Directory. When you undelete a mailbox-enabled user within the mailbox retention period, the user’s access to the mailbox is also restored.

After a user is deleted, the Exchange Server retains the user’s mailbox for a specified period, before permanently deleting the mailbox. If the mailbox retention period has expired, the mailbox access associated with the undeleted user is not recovered. Recovery Manager for Active Directory cannot restore mailboxes that have been permanently deleted.


In the Group Policy Restore Wizard, a GPO link is shown as deleted, but the link actually exists in Active Directory. What's wrong?

If a link’s No Override option or Disabled option has been changed, Recovery Manager for Active Directory treats the link as having been deleted, and assumes that a new link was created with new options. This behavior is by design.


What is a primary restore of the SYSVOL?

A primary restore is intended to recover the initial member of the SYSVOL replica set, only when the entire replica set has been lost. A primary restore should therefore not be used if there are two or more operational domain controllers in the domain. If there are other members in the replica set with which the restored SYSVOL can synchronize, a primary restore should not be performed, as it disrupts the replication of SYSVOL data.

For more information about primary restore, see the Microsoft article “Authoritative, Primary, and Normal Restores” at


How do I change the Backup Agent port number?

Recovery Manager for Active Directory uses a TCP port to communicate with Backup Agent installed on the target domain controllers to be backed up. To change the Backup Agent port number, perform the following procedures.

On each target domain controller to be backed up, perform the following steps:

  1. Start Registry Editor (Regedit.exe), and then locate the registry key:


  2. In the details pane, double-click the ImagePath value, and in the Value data text box, specify the port number in the following way:

    %SystemRoot%\RecoveryManagerAD\ErdAgent.exe -I -P:3899

    In this example, Backup Agent will use port 3899. When finished, click OK.

  3. Close Registry Editor.

  4. Restart the Backup Agent service.

Start the Recovery Manager for Active Directory Console (snap-in), and then perform the following steps:

  1. In the console tree, select the node Recovery Manager for Active Directory, and then on the Action menu, click Settings.

  2. On the Ports tab, select the Connect to Backup Agent using a specific TCP port. check box, and then specify the port number in the Port text box.

  3. Click OK to close the Recovery Manager for Active Directory Properties dialog box.


If you are using a firewall, the specified TCP port must be opened. You must specify the same port number for all target domain controllers to be backed up.
