我们正在尝试显示有关事件消息的所有事件详细信息，我们正在跟踪多条消息，其中一些是eventMessage. 当尝试访问事件关系时，eventMessage我们总是为对话中的所有消息获得相同的事件。
因此，原始事件消息显示最新的事件属性（开始和结束时间、位置等）
我尝试使用 Microsoft Graph Explorer 查看是否有任何方法可以通过使用changeKey项目本身来获取特定事件项目。可悲的是，没有成功。
例如，当尝试通过使用对话 id 过滤并扩展事件关系来访问对话中的所有消息时
GET https://graph.microsoft.com/v1.0/me/messages/?$filter=conversationId eq '<ConversationId>='&$expand=Microsoft.Graph.EventMessage/Event
我们总是为所有消息获得相同的事件。

我们希望每个 eventMessage 都有自己的事件本身的“版本”。在提供的情况下，开始和结束时间应该已更改。访问该webUrl属性时，我们得到了预期的结果。
