outside entity user changes

GW 2014 r2.  Recently,  I have discovered that I cannot change any information for any given users that has been assign to a post office that is setup as an outside entity.  I can create the basic user, ie username.  When I try to edit the record to add the First/Last name, department or any other field and click save, the little spinning wheel on the save button just spins and spins and spins.


Thanks for any ideas.
