Can't remove public folder database because system folders still exist in it

Hi all,

Here is my situation: I have a public folder database that I am trying to decommission and remove (I am decommissioning the Exchange services in one of my 3 Exchange sites). I have run the moveallreplicas.ps1 script against the database to move all of folders to my other public folder databases and it ran without error. I am unable to remove the public folder database though, when I try it gives an error that I can't remove a PF DB with replicas in it. When I run Get-PublicFolderStatistics against the mailbox server that has that database it returns two system folders, \NON_IPM_SUBTREE\OFF LINE ADDRESS BOOK and \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY.

How can I remove these two folders so I can remove this public folder database?

Running Exchange 2010 SP1 RU3.

Thanks, Jason
