GetFolder操作给了我同样的结果。

此错误通常由未经许可的邮箱帐户引起。但我的所有用户都有活跃的Exchange许可证。为什么我会得到这样的ErrorNonExistentMailbox错误响应？

确保运行EWS脚本的帐户具有ApplicationImpersonation权限。因此在这种情况下,您的帐户应该具有ApplicationImpersonation权限。

• 导航到O365>权限>将ApplicationImpersonation添加到HygeneManagement RBAC组中的EAC，然后将自己添加为成员。这将解决此问题。

今后，如果您想要解决ApplicationImpersonation的故障，可以使用EXRCA(https://testconnectivity.Microsoft.com/)>O365选项卡>Microsoft Exchange Web Services Connectivity Tests>选择“服务帐户访问（开发人员）”并运行测试。
