Question

我正在尝试创建一种无需用户交互即可使用Microsoft Graph API订阅Office 365中的邮件事件（新邮件，创建，更新）的应用程序。如果有新邮件，我想向使用C＃MVC5和.Net 4.5构建的应用程序发送通知。我在下面的示例在Github中（使用Daemon Service） Github project Link）但它已内置于.Net Core中。我遇到了另一个使用WebJobs的应用程序，非常接近我的需求
Azure webjobs，但最近两年未更新。我已按照步骤进行操作，但其中大多数与我的Azure开发人员帐户（免费）不匹配。有人可以帮我吗？

应用程序设置：

应用设置：

<add key="tenantId" value="[Tenant_ID]" />
    <add key="clientId" value="[AppID]" />
    <add key="clientSecret" value="[Client Secret]" />
    <add key="webjobs" value="DefaultEndpointsProtocol=https;AccountName=onvidawebjob1aa1b;AccountKey=Z3xewALbEc43gE/dL06HxCGIjVtpaiTkIY4ZolkjZt9Z86xHIZLzMwXBlujNI8/PcTJbM1LIs5KNceVTGgESmA==" />
    <add key="subscriptionblobname" value="subscriptions/subscription1" />
    <add key="notificationurl" value="https://onvidawebjob1.azurewebsites.net/api/HttpTrigger1?code=H7liZOlcQc5qjcZOkRXEb0x4JVqTzoXnrl6mAswsEKl4LlmAYm/ACw==" />

我试图重新创建该应用，但出现问题跟踪

编辑1：

我能够使用Outlook连接器和Office 365 Webhook API（使用Azure逻辑应用程序中提供的默认连接器）完成与here相似的电子邮件接收（无需用户登录）。但是，Outlook连接器每隔x秒（由我设置的自定义值）轮询一次邮箱中的任何更改，但是我希望该服务自动触发Webhook事件而不进行轮询。如果我正确理解，应该是这样-

创建一个注册用于监视事件的Webhook
创建一个使用以上webhook的Outlook连接器。
Outlook连接器在工作流中通知应用程序（REST API调用）。

以下是要考虑的一些关键点：

无论使用哪种语言/平台，使用Microsoft Graph Webhook通知都是相同的。唯一的区别是托管通知端点的方式/位置。
要在没有用户交互的情况下订阅通知，您的应用需要仅应用程序权限

您可能想研究Azure函数；它们提供了一些易于使用的Microsoft Graph绑定：https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-microsoft-graph

通过Microsoft Graph API订阅消息，无需用户交互
