Cannot delete Public Folder that is flagged as Hold for Migration

I am attempting to remove a public folder mailbox per this KB article

http://support.microsoft.com/kb/2786607

Presently there is one Public Folder mailbox that is held for migration.  I decided not to migrate any public folders over because we want to structure it differently.  So I need to remove the mailbox presently there flagged as held.  This is a secondary hierarchy mailbox.  There is no primary.

When I run

Get-Mailbox -PublicFolder | where {$_.IsRootPublicFolderMailbox -eq $False} | Remove-Mailbox –PublicFolder

I receive

Public folder replication has been delayed.  Please wait until replication is complete before you remove this public folder mailbox.  Replication could take up to an hour.  If you remove the mailbox before replication is complete, your public folder deployment could be in an inconsistent state.

I have been unable to find a workaround for this. 

Any thoughts?

Thanks,
