How to create an Outlook "appointment" using DDay.iCal?

I use the DDay library to create an iCal event so that users on my site can add something to their calendar.

I want them to add a meeting, not a meeting request in Office 2010 (and hopefully others). When I use the library and set the method to PUBLISH, it appears as a meeting, but reports that the meeting cannot be found on the calendar. Then, when I do not require a response, the item is deleted and does not remain on the calendar.

If I changed the method to a request, it will appear as a meeting invitation. This will be the best second option, but the 'to' field is empty. If this is the best I can do, how can I set the 'to' field? I probably would have answered that they would respond to themselves.

private static string CreateCalendarEvent( string title, string body, DateTime startDate, double duration, string location, string organizer, string eventId, bool allDayEvent) { // mandatory for outlook 2007 if(String.IsNullOrEmpty(organizer)) throw new Exception("Organizer provided was null"); var iCal = new iCalendar { Method = "PUBLISH", Version = "2.0" }; // "REQUEST" will update an existing event with the same UID (Unique ID) and a newer time stamp. //if (updatePreviousEvent) //{ // iCal.Method = "REQUEST"; //} var evt = iCal.Create<Event>(); evt.Summary = title; evt.Start = new iCalDateTime(startDate); evt.Duration = TimeSpan.FromHours(duration); evt.Description = body; evt.Location = location; evt.IsAllDay = allDayEvent; evt.UID = String.IsNullOrEmpty(eventId) ? new Guid().ToString() : eventId; evt.Organizer = new Organizer(organizer); evt.Alarms.Add(new Alarm { Duration = new TimeSpan(0, 15, 0), Trigger = new Trigger(new TimeSpan(0, 15, 0)), Action = AlarmAction.Display, Description = "Reminder" }); return new iCalendarSerializer().SerializeToString(iCal); }

When I set the organizer to an email address, unlike the test line, it worked fine. I wrote all of this, so I thought I would share it if anyone had the same problem.

My application stopped working when the exchange server was upgraded to Outlook 2010 since 2003. Before the update, PUBLISH worked fine, but now I had to switch to REQUEST
