Outlook 约会 webhook 在创建后立即获取更新

如何解决Outlook 约会 webhook 在创建后立即获取更新

我们的应用程序从 Outlook 订阅了 webhook 通知，我们试图找出原因，当我们在 Outlook 中创建约会时，我们正确地收到了一个创建通知，例如：

    "@odata.type": "#Microsoft.OutlookServices.Notification","Id": null,"SubscriptionId": "xxx","SubscriptionExpirationDateTime": "2021-05-07T05:40:12.6178147Z","SequenceNumber": 5,"ChangeType": 1,"Resource": "https://outlook.office.com/api/v2.0/Users('yyy')/Events('zzz')","ResourceData": {
        "@odata.type": "#Microsoft.OutlookServices.Event","@odata.id": "https://outlook.office.com/api/v2.0/Users('yyy')/Events('zzz')","Id": "zzz","ChangeKey": "key1","InternetMessageHeaders": null,"SingleValueExtendedProperties": null,"InternetMessageId": null,"IsDraft": null,"LastModifiedDateTime": "2021-05-06T05:42:50.128Z"
    }
}

但是在我们收到后续更新通知后一两分钟，即使我们在创建之后没有更改约会

{
    "@odata.type": "#Microsoft.OutlookServices.Notification","SequenceNumber": 7,"ChangeType": 2,"ChangeKey": "key2","LastModifiedDateTime": "2021-05-06T05:45:41.2377626Z"
    }
}

关于为什么会发生这种情况或如何避免更新消息的任何想法或想法将不胜感激。感觉像是在微软方面发生了某种延迟的过程
