我们在 Exchange Online 中创建了一个新的共享邮箱，并为用户分配了完全访问权限和发送权限。当这些用户以共享邮箱的身份向外部电子邮件地址发送邮件时，它可以正常工作。但是当他们尝试向内部用户发送邮件时，他们会收到 NDR（见下文）。
我的所有研究都指向正确设置“发送为”权限。但权限是正确的。
还有其他想法吗？

答案1
您提到您已经正确设置了“发送为”权限，但问题仍然存在。您可以尝试以下一些其他步骤：
确保全局地址列表 (GAL) 已更新。您可以通过在 Outlook 桌面版中下载脱机地址簿来执行此操作。转到“发送/接收”>“发送/接收组”>“下载地址簿”，然后单击“确定”。
尝试使用 Outlook Web Access (OWA) 从共享邮箱发送电子邮件。创建新电子邮件并从“显示发件人”字段中选择具有正确权限级别的用户。如果电子邮件发送成功，则问题可能出在 Outlook 桌面客户端上。
检查用户是否具有共享邮箱的“代理发送”权限。如果没有，请授予他们该权限。有关如何执行此操作的信息，请参阅管理收件人的权限。
如果问题仍然存在，请尝试更新通讯簿，方法是转到“发送/接收”选项卡，然后单击“发送-接收组”>“下载通讯簿”。单击“确定”后，尝试使用共享邮箱从 Outlook 再次发送。
