Show only the meetings where the user is the organizer with EWS

Hello,

is there a way to search all users calendar (the are all in a distribution group) and show only the meetings, where they are the oranizers?

I am using impersonation.

With the following code I can get the organizer of a Meeting:

            //Instantiate the ExchangeService class+ Exchange Certificate Validation + Imparsonate
            ServicePointManager.ServerCertificateValidationCallback = CertificateValidationCallBack;
            ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
            service.Credentials = new NetworkCredential("user", "password", "domain");
            service.AutodiscoverUrl("user@domain", RedirectionUrlValidationCallback);

            //Distinguish Distribution Group
            string distributiongroup = "distributiongroup@domain";

            // Initialize values for the start and end time.
            DateTime startDate = DateTime.Now.AddMinutes(0);
            DateTime endDate = startDate.AddDays(1);

            //Extend the distribution group
            ExpandGroupResults distGroupMembers = service.ExpandGroup(distributiongroup);
            foreach (EmailAddress address in distGroupMembers.Members)
            {
                //Impersonate each distribution group member
                service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, address.Address);

                // Execute the search in the calendar folder and return the view
                CalendarView caledarView = new CalendarView(startDate, endDate);
                caledarView.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);
                FindItemsResults<Appointment> apt = service.FindAppointments(WellKnownFolderName.Calendar, caledarView);

                foreach (Item item in apt.Items)
                {
                    ServiceResponseCollection<GetItemResponse> myColl = service.BindToItems(new[] { new ItemId(item.Id.UniqueId) }, caledarView.PropertySet);
                    foreach (GetItemResponse temp in myColl)
                    {
                        Appointment app = (Appointment)temp.Item;

                        string organizator = app.Organizer.Address;
                     
                        Console.WriteLine(address + "\n" + app.Subject + " " + organizator);
                    }
                }

My goal is to get only the meetings for every user, where he is the organizer.

Can you help me on this one? I have been struggeling for hours to get this...Kind Regards

Ioannis
