microsoft-graph-api - Microsoft 图形通知停止工作

Question

我几个月前为某些收件箱创建了一些订阅，系统成功收到了有关收到电子邮件的通知，订阅也定期更新以增加到期日期。这是我的订阅列表:

https://graph.microsoft.com/v1.0/subscriptions/

{
"@odata.context": "https://graph.microsoft.com/v1.0/$metadata#subscriptions",
"value": [
{
"id": "ef4d00ca-cf0c-4da6-bded-1ab47295e3f5",
"resource": "users/622eee14-9413-49e3-ac53-10148eba09be/messages",
"applicationId": "281e7aa8-7ef8-4a02-9195-83ffb149d95c",
"changeType": "created",
"clientState": null,
"notificationUrl": "https://...",
"expirationDateTime": "2019-12-03T23:00:03.0238504Z",
"creatorId": "2ca67f35-32ba-4ef5-99ab-6686a93e0007"
},
{
"id": "6f056383-df34-47b5-aaf2-dce3fca1c511",
"resource": "users/3ccbd0c8-f11e-4bac-99df-27b78be74aaa/messages",
"applicationId": "281e7aa8-7ef8-4a02-9195-83ffb149d95c",
"changeType": "created",
"clientState": null,
"notificationUrl": "https://...",
"expirationDateTime": "2019-12-03T23:00:01.4332477Z",
"creatorId": "2ca67f35-32ba-4ef5-99ab-6686a93e0007"
}
]
}

但是从今天(2019-12-02)开始系统停止接收通知。然后我用我的测试账户创建了订阅订阅已成功创建，打电话https://graph.microsoft.com/v1.0/subscriptions/ , 我已经收到回复了

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#subscriptions",
    "value": [
        {
            "id": "dfefbb04-887f-439f-bb09-a6075eeca8cd",
            "resource": "users/ebaeb8ab-44c1-40e1-8725-635759c035db/messages",
            "applicationId": "57afcb67-6089-4abc-bba8-2470ce9c22ec",
            "changeType": "created",
            "clientState": null,
            "notificationUrl": "https://63efa1ea.ngrok.io/api/Core/MailNotification/Listen",
            "expirationDateTime": "2019-12-04T13:10:14.2380272Z",
            "creatorId": "6a046ec1-ec01-43de-83b8-0e0696e89ecf"
        }
    ]
}

我已尝试将电子邮件发送到上述邮箱，但仍然没有收到通知。Ms Graph 有什么变化吗？有没有办法解决这个问题，我可以在 Azure 门户或其他地方看到一些日志，MS Graph 是否尝试向我发送通知？或者它只是突然停止工作？

Answer 1

从 2019 年 11 月 30 日起，似乎服务质量下降影响了 Microsoft Graph Exchange 服务。这似乎已解决，如 comment 所示.
