Remove Multiple Public Folders from a Public Folder Database

Applies to: Exchange Server 2010

Topic Last Modified: 2011-03-19

You can use the Shell to remove all the public folders from a public folder database.

This procedure removes all the user and system public folders from a public folder database. If you only want to remove one public folder from a public folder database, see Remove Public Folders. This procedure is required if you are removing the last public folder database in your Exchange organization. For detailed instructions about how to remove public folder databases, see Remove Public Folder Databases.

Bb201664.Caution(en-us,EXCHG.140).gifCaution:
If you want to remove a public folder database on a specific server running Microsoft Exchange Server 2010, you must move all the replicated public folders to another database by using the MoveAllReplicas.ps1 script. The MoveAllReplicas.ps1 script changes the server in the replica list for all public folders to another server. After the folders have been replicated, you can remove the public folder database from the Exchange 2010 server. If you delete replicated public folders before you move the public folders, the deleted public folders may replicate before the public folder database can be deleted. In this case, the public folder data is also deleted from the other databases. For more information, see Move Public Folder Content from One Public Folder Database to Another Public Folder Database.
