如何在Microsoft Graph API回复邮件时设置重要性

你可以直接在请求负载的message对象中添加importance属性来设置邮件重要性，取值包括low、normal、high，设置为high即可满足高重要性需求。修改后的请求示例如下：

POST https://graph.microsoft.com/v1.0/me/messages/AAMkADA1MTAAAAqldOAAA=/reply
Content-Type: application/json

{
  "message":{  
    "toRecipients":[
      {
        "emailAddress": {
          "address":"samanthab@contoso.onmicrosoft.com",
          "name":"Samantha Booth"
        }
      },
      {
        "emailAddress":{
          "address":"randiw@contoso.onmicrosoft.com",
          "name":"Randi Welch"
        }
      }
     ],
     "importance": "high"
  },
  "comment": "Samantha, Randi, would you name the group please?" 
}

这种方式基于原有的Reply API调用，不会丢失对话ID，Outlook依然能将回复显示为邮件线程。
