title: :iCal Event not added into organizer calendar
body: <p>I am creating ics file with 2 attendee and a organizer. </p>
  
  <p>Event is properly creating for both attendees and response is also received when they accept/reject the event. I am sending same invite to organizer as well. On organizer end, event is not adding into their calendar (accept/reject buttons are grayed out). Following two messages are showing:</p>
  
  <ol>
  <li>At the meeting organizer, you do not need to respond to the meeting.</li>
  <li>Meeting cannot be found in the Calendar.</li>
  </ol>
  
  <p>How I can change the event so that it also create in organizer calendar?</p>
