[EWS] Setting attendee status in calendar events RRS feed

  • Question

  • I know I've asked this before, but I'm getting a bit desperate so I wanted to make sure there are no updates that would affect this. I've got an EWS application (direct XML, not the managed API) that migrates calendar events into Office 365. I am setting attendees by adding "<t:attendee> tags to the XML. Works fine but I really need to be able to set the attendee status to "accepted", "tentative", "declined", etc. I can do this in MAPI by setting various properties of the entries in the recipient table.  But for this application, I need to use EWS exclusively. I assume there is no way I can do this via the XML? What about using an ExtendedProperty? I know how to do that for properties of the event, but I would need an example of how to set the Recipient Table and properties within that. Any help would be greatly appreciated.
