Hi,

I've got problem with sending free appointment to Exchange. When I send standard meeting request there is no problem - attendees see tentative event and after acceptation they see busy event in calendar.

I want now send from code appointment that will be set as free in calendar at once for attendees. If I send that request from Outlook there is no problem. But when I save that message as text (.ics file), copy content to string and send it from code - the appointment is tentative (before acceptation) or busy (after acceptation by default) after receive.

I use following e-mail content:
