The possible values are: none, organizer, tentativelyAccepted, accepted, declined, notResponded.To differentiate between none and notResponded:  none \u2013 from organizer's perspective. This value is used when the status of an attendee/participant is reported to the organizer of a meeting.  notResponded \u2013 from attendee's perspective. Indicates the attendee has not responded to the meeting request.  Clients can treat notResponded == none.  As an example, if attendee Alex hasn't responded to a meeting request, getting Alex' response status for that event in Alex' calendar returns notResponded. Getting Alex' response from the calendar of any other attendee or the organizer's returns none. Getting the organizer's response for the event in anybody's calendar also returns none."
