Summary: How to designate a passive copy of an Exchange 2016 mailbox database as the new active copy.

Activating a mailbox database copy is the process of designating a specific passive copy as the new active copy of a mailbox database. This process is referred to as a database switchover. A database switchover involves dismounting the current active database and mounting the database copy on the specified server as the new active mailbox database copy. The database copy that will become the active mailbox database must be healthy and current.

  1. In the EAC, go to Servers > Databases.

  2. Select the database whose copy you want to activate.

  3. In the Details pane, under Database Copies, click Activate under the database copy you want to activate.

  4. Click yes to activate the database copy.

This example activates and mounts a copy of the database DB4 hosted on MBX3 as the new active mailbox database. This command makes DB4 the new active mailbox database, and it doesn't override the database mount dial settings on MBX3.

Move-ActiveMailboxDatabase DB4 -ActivateOnServer MBX3 -MountDialOverride:None

This example performs a switchover of the database DB2 to the Mailbox server MBX1. When the command completes, MBX1 hosts the active copy of DB2. Because the MountDialOverride parameter is set to None, MBX1 mounts the database using its own defined database auto mount dial settings.

Move-ActiveMailboxDatabase DB2 -ActivateOnServer MBX1 -MountDialOverride:None

This example performs a switchover of the database DB1 to the Mailbox server MBX3. When the command completes, MBX3 hosts the active copy of DB1. Because the MountDialOverride parameter is specified with a value of Good Availability, MBX3 mounts the database using a database auto mount dial setting of GoodAvailability.

Move-ActiveMailboxDatabase DB1 -ActivateOnServer MBX3 -MountDialOverride:GoodAvailability

This example performs a switchover of the database DB3 to the Mailbox server MBX4. When the command completes, MBX4 hosts the active copy of DB3. Because the MountDialOverride parameter isn't specified, MBX4 mounts the database using a database auto mount dial setting of Lossless.

Move-ActiveMailboxDatabase DB3 -ActivateOnServer MBX4

This example performs a server switchover for the Mailbox server MBX1. All active mailbox database copies on MBX1 will be activated on one or more other Mailbox servers with healthy copies of the active databases on MBX1.

Move-ActiveMailboxDatabase -Server MBX1

This example performs a switchover of the database DB4 to the Mailbox server MBX5. In this example, the database copy on MBX5 has a replay queue greater than 6. As a result, the SkipLagChecks parameter must be specified to activate the database copy on MBX5.

Move-ActiveMailboxDatabase DB4 MBX5 -SkipLagChecks

This example performs a switchover of the database DB5 to the Mailbox server MBX6. In this example, the database copy on MBX6 has a ContentIndexState of Failed. As a result, the SkipClientExperienceChecks parameter must be specified to activate the database copy on MBX6.

Move-ActiveMailboxDatabase DB5 MBX6 -SkipClientExperienceChecks

To verify that you've successfully activated a mailbox database copy, do one of the following:

  • In the EAC, navigate to Servers > Databases. Select the appropriate database, and in the Details pane, click View details to view the database copy properties.

  • In the Exchange 관리 셸, run the following command to display status information for a database copy.

    Get-MailboxDatabaseCopyStatus <DatabaseCopyName> | Format-List
