Cannot delete Exchange 2007 Public Folder Database

I am trying to retire one of my 3 public folder servers.  I have moved all the replicas already.  Get-PublicFolderStatistics -server 'servername' returns only 1 folder.

EX:/o=CONTOSO/ou=Exchange Administrative  2847                                   6/8/2015 8:45:44 PM
Group (FYDIBOHF23SPDLT)

When I try to delete it; i get an error that says doesn't exist on the server.
