I have some recurrent appointments in an  Exchange 2013 public folder:  the user who created them has been removed from the system.  Any attempt to delete the appointments results in an "Unknown error".

Any suggestions how I might delete these orphans?

It does appear that I only have a problem with one orphans appointments:  other orphan's appointments do seem to be deletable.  So maybe the problem here isn't the appointments orphan status.
