If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.
如果您在推迟或取消一个提醒后看到此消息，并且这是您不想向其添加或编辑事件的日历，则可将此日历标记为只读，以免将来出现类似情况。如果要这么做，请在日历或任务视图的列表中右键单击此日历，设定日历的属性。
