This cmdlet is available only in on-premises Exchange Server 2013.

Use the Dismount-Database cmdlet to dismount a database on a computer running Microsoft Exchange Server 2013 that has the Mailbox server role installed. You can run this command only if the Microsoft Exchange Information Store service is running.

This example dismounts the database MyDatabase.

NoteNote:
Regardless of where you run this cmdlet, it operates against the server hosting the active copy of the database.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Mailbox databases" entry in the Recipients permissions topic.

Identity

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseIdParameter

The Identity parameter specifies the GUID or distinguished name (DN) that represents a specific database.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

DomainController

Optional

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.
