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
