  • A Recurring meeting without an end date is not a bug and doesn't need to be fixed it perfectly valid why do you want to do this? its important to understand that recurring appointments are only stored as one Item in the Exchange Store and the recurrence is just a patterned stored in a property on that item so there is nothing to gain from doing this. Bascially to find appointments with these property just you can try something like this

            ExtendedPropertyDefinition isRecurring = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.Appointment, 33315, MapiPropertyType.Boolean);
            SearchFilter sfSearchFilter1 = new SearchFilter.IsEqualTo(isRecurring, true);
            SearchFilter sfSearchFilter2 = new SearchFilter.IsEqualTo(ItemSchema.ItemClass, "IPM.Appointment");
            SearchFilter sfCol = new SearchFilter.SearchFilterCollection(LogicalOperator.And) { sfSearchFilter1, sfSearchFilter2 };
            ItemView iv = new ItemView(10000);
            PropertySet psPropSetmaster = new PropertySet(BasePropertySet.FirstClassProperties);
            iv.PropertySet = psPropSetmaster;
            FindItemsResults<Item> fiMasters = cfCalendarFolder.FindItems(sfCol, iv);
            foreach (Item itItem in fiMasters)
              if (itItem is Appointment)
                catch (Exception e)
                  if (e.Message != null)
                Appointment apAppointment = (Appointment)itItem;
                if (apAppointment.AppointmentType == AppointmentType.RecurringMaster)
                  if (apAppointment.Recurrence.HasEnd == false)

    This is more usefull however to identify recurring appointments that have expired.
