Hi, we have Exchange 2007 and Exchange 2010 environment, There is an Public Folder database that I replicated it with Exchange 2007 Public Folder database and then I stopped it. When I check I see there is 150 GB size of Public Folder Database of Exchange 2010, Now I want to delete this Exchange 2010 Public Folder database but I can't delete it because it has data, How can I remove this Public Folder database (without corrupt Exchange 2007 Public Folder Database) ? Thanks in advance.

Hi mscik, There are replica PFs left in your Ex2010 public folder database. Prior to deleting it - try to cancel this replication. 0. Get the PF Database mounted 1. Navigate with EMShell to: cd $env:exchangeinstallpath\scripts 2. Collect if and what is still replicating with this PF DB: Get-PublicFolder \ -Recurse | ft name,parentpath,replicas If you find your Ex2010 in the list - that's your goal. 3. Move everything to your Ex2007 cd $env:exchangeinstallpath\scripts MoveAllReplicas.ps1 -Server ex2010name -NewServer ex2007name After somewhile command #2. must show no Ex2010 among the replicated servers Youll also need to make sure that the server is not the OAB generation server for any Offline Address Books that are also being published to public folders. 4. If necessary move the OAB generation to another mailbox server: Move-OfflineAddressBook "Default Offline Address List" -Server ex2007name Once all of these conditions have been met you should be able to remove the public folder database. * If you still cant remove it and youre sure the public folder database contains no more replicas you can use ADSIEdit to remove the public folder database from the organization. 5. Launch adsiedit.msc, connect to "Configuration" context, Navigate to "CN=Configuration / CN=Services / CN=Microsoft Exchange / CN=YourOrganizationName / CN=Administrative groups / CN=Exchange Administrative Group / CN=Databases" and remove CN=YourEx2010PublicFolderDatabaseName.
