Each mailbox database is configured with a default public folder database. MAPI client applications, such as Microsoft Office Outlook, open a connection to the default public folder database and perform all hierarchy-based operations against the server that contains that database. These operations include viewing public folders, creating and deleting public folders, and querying for the location of public folder content.

This topic explains how to use Exchange Management Console or the Exchange Management Shell to change the default public folder database for a mailbox database.

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

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

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

Also, to perform this procedure, you must have more than one public folder database. For more information about how to create a public folder database, see How to Create a New Public Folder Database.

  1. Start the Exchange Management Console.

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

  3. In the result pane, select the Mailbox server on which the database resides.

  4. In the work pane, select the mailbox database for which you want to change the default public folder database.

  5. In the action pane, under the mailbox database name, click Properties.

  6. In <Mailbox Database Name> Properties, click the Client Settings tab.

  7. Next to the Default public folder database box, click Browse.

  8. In Select Public Folder Database, select the public folder database from the list of public folder databases, and then click OK.

  9. Click OK.

  • To set the public folder database named PublicFolderDB1 as the default public folder database for the mailbox database named Mailbox Database, run the following command.

    Set-MailboxDatabase -Identity "Mailbox Database" -PublicFolderDatabase "PublicFolderDB1"
