EWS: How to update occurrence in recurrent series RRS feed

  • Question

  • I tried to create using EWS library recurrent appointment (successfull). After I need to move one occurrence in series for one hour. I can get (using FindAppointments method) all occurrences and find needed one. I set new Start and End dates for it, but during executing Update method of Appointment I get error message:

    "Single calendar item or recurring master is expected." 

    How can I modify occurrence in the recurrent series of appointments (make not deleted exception)?

  • Resolved. Problem was in assigning iCalUid property of Appointment (even it was the same as new value). After removing setting of iCalUid, Update method works.
