The server will not allow an attendee to store an event that has another 
user (also hosted on the server) as an organizer, if the organizer's copy 
of the event is not present. In your case, create the initial event in a 
server calendar rather than a local calendar as the organizer - then it 
will propagate correctly to all attendees and stay in sync as changes are
