Outlook升级OAuth2.0发送邮件提示The AadGuestPft token doesn't contain the permissions required by the target API for calling app '00000003-0000-0000-c000-000000000000'.

Question

你好，我们把Outlook邮件服务的功能升级认证方式为OAuth2.0，我们注册了一个Microsoft Entra帐号，获取token也成功，但我们用这个Outlook发邮件时，返回错误:401:The AadGuestPft token doesn't contain the permissions required by the target API for calling app '00000003-0000-0000-c000-000000000000'.能帮我看一下是少了那些权限？还是少了那些配置问题吗？以下是我的应用程序截图

1：注册 应用程序

6：outlook授权-用 授权code获取access_token

"error": {

    "code": "AuthOMMissingRequiredPermissions",

    "message": "The AadGuestPft token doesn't contain the permissions required by the target API for calling app '00000003-0000-0000-c000-000000000000'.",

    "innerError": {

    }

}
```}
为什么发送不了？求解？？？？
