This topic explains how to use the Exchange Management Console or the Exchange Management Shell to dismount a mailbox or public folder database in a storage group on a Microsoft Exchange Server 2007 Mailbox server.

To perform this procedure, the account you use must be delegated the following:

  • Exchange Server Administrator role and local Administrators group for the target server

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

You can dismount a database only if the Microsoft Exchange Information Store service is running.

  1. In the console tree, expand Server Configuration, and then click Mailbox.

  2. In the result pane, select the server on which the mailbox or public folder database is located.

  3. In the work pane, select the database that you want to dismount.

  4. In the action pane, click Dismount Database.

  5. A warning appears asking if you want to dismount the database. Click Yes.

  • Run the following command:

    Dismount-Database "My Database"

    Where My Database is the name of the mailbox database or the public folder database that you want to dismount.

For detailed syntax and parameter information, see the Dismount-Database reference topic.
