如何使用Java EWS api删除整个Exchange日历活动？

Question

我已经编写了如下代码，它删除了具有当前日期的约会，但有一种方法可以一次删除整个日历约会。提前致谢

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，您有两个选项是批量删除从FindItems返回的项目（查找约会将扩展定期约会，如果要删除所有不想要的项目，只需删除主实例和单个实例见https://msdn.microsoft.com/en-us/library/office/dn626016(v=exchg.150).aspx#bk_deleteews）

另一种选择是使用空文件夹操作，该操作应该在2013年及以上https://msdn.microsoft.com/en-us/library/office/ff709484%28v=exchg.150%29.aspx上运行
