I'm having the same problem too and it is driving me crazy!  I keep getting emails telling me that payroll is due.  Oh, and by the way, the action to delete the client is not in my dropdown is not there, all that is there is create a tax return or make it inactive.  This is really, really stupid.  None of the recommendations are even valid solutions.  I need to delete this client and I need to stop getting notifications for it-yes, I have removed my email from all necessary places.
