When a user sends out a calendarinvite not all the answers is showing up in his list of accepted/ non accepted list.
Outlook 2007/2010 - Accept - Edit before send > Works, the answer is sent and shows.
Outlook 2007/2010 - Accept - Send response now > Not working, the answer is not sent.
Outlook 2007/2010 - Accept - Do not send response > Not working, no response is sent.
