小编Nin*_*Ak3的帖子

我在遇到问题https://graph.microsoft.com/v1.0/users/ <用户id > / sendmail的。

我收到 202 Accepted 作为响应，但是当我浏览到上面的用户邮箱时，我收到如下的传递失败通知：

Delivery has failed to these recipients or groups:

<username>@outlook.com
Your message wasn't delivered because the recipient's email provider rejected it.

Remote Server returned '550 5.7.708 Service unavailable. Access denied, traffic not accepted from this IP. For more information please go to http://go.microsoft.com/fwlink/?LinkId=526653 AS(7171) [SYBPR01MB4428.ausprd01.prod.outlook.com]'

当我登录 Outlook 并从 < userId > 的 Outlook向 < username >@outlook.com发送电子邮件时，电子邮件已成功发送。
