I want to create meeting appointment request like shown in image using c# (wpf app) and open it in outlook window.

also want to save appointment into calendar

What I have tried:

Microsoft.Office.Interop.Outlook.Application outlookApplication = new Microsoft.Office.Interop.Outlook.Application(); ;
            Microsoft.Office.Interop.Outlook.AppointmentItem newAppointment = (Microsoft.Office.Interop.Outlook.AppointmentItem)outlookApplication.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem);

            newAppointment.Start = DateTime.Now.AddHours(2);
            newAppointment.End = DateTime.Now.AddHours(3);
            newAppointment.Location = "http://xyz.co/join/7235253940223 ";
            newAppointment.Body ="jigi is inviting you to a scheduled XYZ meeting. ";
            newAppointment.AllDayEvent = false;
            newAppointment.Subject = "XYZ";
            newAppointment.Recipients.Add("Roger Harui");
            Microsoft.Office.Interop.Outlook.Recipients sentTo = newAppointment.Recipients;
            Microsoft.Office.Interop.Outlook.Recipient sentInvite = null;
            sentInvite = sentTo.Add("Holly Holt");
            sentInvite.Type = (int)Microsoft.Office.Interop.Outlook.OlMeetingRecipientType.olRequired;
            sentInvite = sentTo.Add("David Junca ");
            sentInvite.Type = (int)Microsoft.Office.Interop.Outlook.OlMeetingRecipientType.olOptional;
            sentTo.ResolveAll();
            newAppointment.Save();
            newAppointment.Display(true);

               oAppointment.Body = "Please contact customer  to return their loan device.";
               oAppointment.Start = Convert.ToDateTime(DateTime.Now.AddHours(1));
               oAppointment.End = Convert.ToDateTime(DateTime.Now.AddDays(1));
               oAppointment.ReminderSet = true; // Set the reminder
               oAppointment.ReminderMinutesBeforeStart = 15; // reminder time
               oAppointment.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceHigh; // appointment importance

Some of the reasons for my downvote
- AddDays returns a DateTime so there is no need to convert the result to a DateTime
- If you are going to convert anything to a DateTime you should use TryParse or TryParseExact to avoid the risk of exceptions.
- An uncommented code dump does not make a good solution
- You have not set the MeetingStatus option so this won't work properly

Solution 1

How to: Create a Meeting Request, Add Recipients, and Specify a Location[^]:
To set an appointment item as a meeting request, you must set the MeetingStatus property to olMeeting.

C#

newAppointment.MeetingStatus = Microsoft.Office.Interop.Outlook.OlMeetingStatus.olMeeting;
