[EWS] Setting ResponseType in calendar event RRS feed

  • Question

  • I am using XML/SOAP (not the managed API) to create calendar events in Office 365. For attendees, I need to set the status (accepted, declined, etc.).  In the other direction, I can read this property in ResponseType. From what I gather, this is read-only, and I cannot set it, even though when I do, I get no error from Exchange - it is just ignored:

    <t:Name>John Smith</t:Name>

    Am I correct that there is no way that I can set this property?  How about using extended MAPI properties?  When I tried using "ExtendedProperty" inside the Attendee, I got a schema violation.  Can you show me how I can do this?
