New-MailContact - 错误消息：无法找到企业组织容器

Question

我正在进行跨林迁移，我编写了此脚本以便于迁移通讯组。我已经对它进行了测试，它可以在一个组中运行。该脚本会到达源域并获取LegacyExchangeDN以及该组上的所有SMTP地址。然后，它通过邮件启用使用ADMT迁移的目标域中的组，并添加其正常运行所需的Exchange属性。最后，该脚本从源域中删除该组并创建一个邮件联系人，以便仍在该组织中的用户可以在GAL中查看该组。我添加了处理作为批处理作业运行的逻辑，现在我收到了这个错误：

我发现的Google搜索似乎都不适用于我的情况。有什么想法为什么创建联系人的功能导致此错误？
