title: When creating an iCal event on behalf of an organizer and email it to him, no "Add to calendar" or "RSVP" wrappers appear
body: <p>I'm creating the iCal using ical4j and sending it using Java Mail API 1.4.7. When sending it both to google.mail and outlook.com the organizer receives the email textual part only. All other recipients receive the email wrapped with the "Add to calendar" or "RSVP" buttons (for attendees).</p>
  
  <p>If remove the recipient email from the organizer property, then he receives the email with the wrappers, but then the meeting has no organizer...</p>
  
  <p>My problem with this, is that the organizer I created the event on behalf of, does not get the event created on his calendar.</p>
  
  <p>That's the email sent:</p>
