I am trying to uninstall Exchange 2010, before installing a new instance of Exchange 2010 SP1 on a different server. (Our production Exchange server is 2003) We have met all of the Mailbox uninstall prereqs except for the following: Error: Uninstall cannot continue. Database 'Public Folder Database 1579722947': The public folder database "Public Folder Database 1579722947" contains folder replicas. Before deleting the public folder database, remove the folders or move the replicas to another public folder database. For detailed instructions about how to remove a public folder database, see http://go.microsoft.com/fwlink/?linkid=81409&clcid=0x409 . Recommended Action: We have been able to delete all Public Folders in the 2010 storage group except for the one (previously replicated) folder - "Internet Newsgroups". How can I delete this folder without impacting public folders on the production Exchange 2003 server? We have: verified permissions to the public folder removed replication for the folder on (on the Exch 2010 server) tried PowerShell scripts: RemoveReplicaFromPFRecursive Get-PublicFolder -Server "\" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server -Recurse -ErrorAction:SilentlyContinue

Your last PowerShell command isn't right. There is no server "\". In Exchange Management Shell go to the Scripts subdirectory under where you installed Exchange and run the command: .\RemoveReplicaFromPfRecursive.ps1 -ServerToRemove EXCHANGE2010SERVERNAME -TopPublicFolder "\Internet Newsgroups" Then run this command: Get-PublicFolder -Identity "\Internet Newsgroups" -Server EXCHANGE2010SERVERNAME | FL Identity,Replicas and verify that this subtree has no replicas on the Exchange 2010 server. It there are no replicas and the problem still exists, then you may have replicas of system folders. Run this: Get-PublicFolder -Identity "\NON_IPM_SUBTREE" -Server EXCHANGE2010SERVERNAME | FL Identity,Replicas and see.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Delete the Public Folder Database from Adsiedit.msc for Exchange 2010 Configuration...>Services...>Microsoft Exchange...>ORG..>Administrative Group...>Exchange Administrative Group...>Database...>Public Folder Database (Delete the folder) You are ready to GO.... Cheers,Gulab | Skype: gulab.mallah

We have relicas. How can we resolve/remove them to delete the Public Folder?

Hi Helper m0nkey, Are you the OP? Rainmanjam, "The Internet Newsgroups public folder cannot be deleted".
