列表非常感谢Glen Scales为我指出了正确的方向
检索约会时，我使用了以下代码：
CalendarFolder calendar = CalendarFolder.Bind(_service, new FolderId(WellKnownFolderName.Calendar, resourceId), PropertySet.IdOnly);
CalendarView cView = new CalendarView(startDate, endDate, _maxAppointments);
cView.PropertySet = new PropertySet(PropertySet.IdOnly);
FindItemsResults<Appointment> appointments = calendar.FindAppointments(cView);
我建议您启用跟踪并发布跟踪响应，这可能会告诉您更多有关错误发生原因的信息。@GlenScales我添加了跟踪。仍然不确定这为什么不起作用。您是在尝试修改原始约会还是副本？例如，您似乎在尝试修改位于会议室的约会实例ndar，即使你模拟组织者也不起作用。唯一可以修改的副本是存储在组织者日历中的原始项目。@GlenScales啊，好吧，可能是这样，我是个新手，我不知道两者之间有什么不同。非常感谢，我必须看看如何找到原始会议.@GlenScales就是这样，非常感谢！IsMeeting是真的
