如何使用Java EWS API删除整个Exchange Calender活动

Question

我已经写了以下代码，该代码删除了具有当前日期的约会，但是有一种方法可以一次删除整个日历约会。预先感谢

epublic static HashSet<String> userEventEws(ExchangeService service)  {
    HashSet<String> listSubject = new HashSet<String>();
        Calendar yesterday = Calendar.getInstance();
        Calendar now = Calendar.getInstance();
        yesterday.add(Calendar.DATE, -1);
        now.add(Calendar.DATE, 1);
        Date startDate = yesterday.getTime();
        Date endDate = now.getTime();
        try {
            CalendarFolder calendarFolder = CalendarFolder.bind(service, WellKnownFolderName.Calendar, new PropertySet());
            CalendarView cView = new CalendarView(startDate,endDate);
            cView.setPropertySet(new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End));// we can set other properties 
            // as well depending upon our need.
            FindItemsResults appointments = calendarFolder.findAppointments(cView);
            List <Appointment>appList = appointments.getItems();
            for (Appointment appointment : appList) {
                listSubject.add(appointment.getSubject().trim());
                appointment.delete(DeleteMode.HardDelete);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    return listSubject;
}

通常，您拥有的两个选项是您可以从Finditems删除您返回的项目（查找约会将扩展重复的约会，如果您想删除所有不删除所有项目想要做只删除主实例，而是请参阅https://msdn.microsoft.com/en-us/library/library/office/dn626016(V=EXCHG.150).aspx#bk_deleteews）

）

另一个选项是使用空文件夹操作，该文件夹操作应在2013年和更高版本https://msdn.microsoft.com/en-us/library/library/ffkice/ff709484(v=exchg.150).aspx9.aspx
