OneDrive教育版账号使用Azure Portal注册的应用在授权时报错AADSTS650051解释

完整错误为：   `AADSTS650051: Using application 'AppName' is currently not supported for your organization contoso.com because it is in an unmanaged state. An administrator needs to claim ownership of the company by DNS validation of contoso.com before the application AppName can be provisioned.` 主要原因是学校并没有按照微软的要求给域名增加DNS验证，所以这种账号没有办法使用Azure Portal。只有让学校相关负责人处理。 详细解释参考[这里](https://learn.microsoft.com/en-us/azure/active-directory/external-identities/troubleshoot#you-receive-an-aadsts65005-error-when-you-try-to-sign-in-to-an-azure-resource)。
