If you are migrating from an earlier version of Exchange to a newer version , you may come across a situation where you are not able to decommission the old exchange server due to the inability to delete the Public Folder databases with the below error message.

Public Folder Database 0206806109
Failed
Error:
The public folder database “Public Folder Database 0206806109” 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.

You may opt to use the ADSI edit to forcibly delete the Public folder. But , I would not recommend this approach as the ADSI Tool there is no error check or validation is performed.

You can use the below powershell commands to safely delete the replicas of the remaining Public folders and System public folders after ensuring all the needed Public Folders are migrated to the new exchange servers.

Get-PublicFolder-ServerExch-2010 "\NON_IPM_SUBTREE"-Recurse-ResultSize:Unlimited | Remove-PublicFolder-ServerExch-2010-Recurse-ErrorAction:SilentlyContinue

Now you could remove the Publice folder dataabsae
