title: Get the organizer's calendar appointment using EWS for Exchange 2010
body: <p>I have an synchronization application with sync appointments with Exchange 2010, and i have some questions.</p>
  
  <ol>
  <li>UserA creates an appointment and add UserB as attendee, this means UserA is the organizer of the appointment and UserB outlook calendar will have an appointment entry created.</li>
  <li>UserA and UserB calendar appointment will have their own IDs (UniqueID).</li>
  <li>If for example i am only given the ID (UniqueID) of UserB's calendar appointment, is that a method to retrieve UserA's calendar appointment? Because i think they should be some link between the organizer and the attendees appointment, i just don't know how.</li>
  </ol>
