            meetingId = meeting.Id.ToString();

            // Verify that the meeting was created.

In that case you need to SendAs the user you want the invitations to come from you can do this either by using Impersonation https://msdn.microsoft.com/en-us/library/office/dd633680(v=exchg.80).aspx  or if you have Full/SendAS rights to the Organizers Mailbox you want to send from then you need to set the save location to the calendar or the Organizer you want to use. eg

            Appointment apt = new Appointment(service);
            apt.Subject = "Test SendAs";
            apt.RequiredAttendees.Add("1@dom.com");
            apt.RequiredAttendees.Add("user2@dom.com");
            apt.Start = DateTime.Now;
            apt.End = DateTime.Now.AddHours(1);
            FolderId SendAsOrgCalendar = new FolderId(WellKnownFolderName.Calendar, "sendas@domain.com");
            apt.Save(SendAsOrgCalendar, SendInvitationsMode.SendToAllAndSaveCopy);

 In EWS the Organizer property is Read-only and will be set to the Creator of the appointment at the time or creation  so meeting.Organizer.Name = "Test"; is not a valid operation.
