获取与事件关联的事件消息

Question

event和event message之间的关系是什么

如何获取与事件相关的事件消息？

在get event message中使用event.id我得到404 NOT FOUND

GET https://graph.microsoft.com/v1.0/me/messages/<Event ID>

返回

{
    "error": {
        "code": "ErrorItemNotFound",
        "message": "The specified object was not found in the store.",
        "innerError": {
            "request-id": "59e0ce99-6aeb-4ad8-b5bc-d498d375538f",
            "date": "2018-07-10T08:01:48"
        }
    }
}
