Exchange WS notification

Доброго всем дня.

Хочу использовать Exchange WS notification:

Делаю соединение:

private bool InitEWS()
        {
            if (_service != null) return true;
            ServicePointManager.ServerCertificateValidationCallback = CertificateValidationCallBack;
            try
            {
                switch (comboBoxExchangeVersion.Text)
                {
                    case "Exchange2007_SP1": _service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); break;
                    case "Exchange2010": _service = new ExchangeService(ExchangeVersion.Exchange2010); break;
                    case "Exchange2010_SP1": _service = new ExchangeService(ExchangeVersion.Exchange2010_SP1); break;
                    case "Exchange2010_SP2": _service = new ExchangeService(ExchangeVersion.Exchange2010_SP2); break;
                    default: _service = new ExchangeService(); break;
                }
            }
            catch (Exception ex)
            {
                System.Windows.Forms.MessageBox.Show(ex.Message, "Failed to create service",
                    MessageBoxButtons.OK, MessageBoxIcon.Error);
                return false;
            }


            if (!String.IsNullOrEmpty(textBoxUsername.Text))
            {
                _service.Credentials = new WebCredentials(textBoxUsername.Text, textBoxPassword.Text);
            }

            _service.TraceListener = _traceListener;
            _service.TraceFlags = TraceFlags.All;
            _service.TraceEnabled = true;

            try
            {
                _service.AutodiscoverUrl(textBoxMailbox.Text, RedirectionUrlValidationCallback);
            }
            catch (Exception ex)
            {
                System.Windows.Forms.MessageBox.Show(ex.Message, "Failed to autodiscover URL",  MessageBoxButtons.OK, MessageBoxIcon.Error);
                return false;
            }
            return true;
        }

и подписываюсь

   FolderId[] folders=new FolderId[1];
   folders[0] = new FolderId(WellKnownFolderName.Inbox);
   _subscription = _service.[b]SubscribeToStreamingNotifications[/b](folders, SelectedEvents());

private EventType[] SelectedEvents()
        {
            // Read the selected events

            if (checkedListBoxEvents.CheckedItems.Count < 1)
                return null;
            EventType[] events = new EventType[checkedListBoxEvents.CheckedItems.Count];

            for (int i = 0; i < checkedListBoxEvents.CheckedItems.Count; i++)
            {
                switch (checkedListBoxEvents.CheckedItems[i].ToString())
                {
                    case "NewMail": { events[i] = EventType.NewMail; break; }
                    case "Deleted": { events[i] = EventType.Deleted; break; }
                    case "Modified": { events[i] = EventType.Modified; break; }
                    case "Moved": { events[i] = EventType.Moved; break; }
                    case "Copied": { events[i] = EventType.Copied; break; }
                    case "Created": { events[i] = EventType.Created; break; }
                    case "FreeBusyChanged": { events[i] = EventType.FreeBusyChanged; break; }
                }
            }

            return events;
        }

ПРОБЛЕМА - Я получаю только сообщения о изминении для того пользователя с которым я делаю соединение!

НАДО - смотреть для всех !!!

СПАСИБО!
