查找组织范围内的 Microsoft 团队（包括来宾）

查找组织范围内的 Microsoft 团队（包括来宾）

有些人可能已经阅读过我之前关于在团队中寻找嘉宾的文章，请参阅链接。

不幸的是，使用“普通”团队 cmdlet 只能删除基于用户的查询，因此如果我的用户不是团队成员，那么我也找不到 O365 组。
所以我寻找另一个解决方案。 在互联网上我很快找到了这个链接。

我花了很长的时间，但现在我必须重建和调整我的完整脚本，因为我不再想与 get-team 合作（这并不意味着它很糟糕） .

当然，在执行脚本之前，必须先连接到 Exchange Online。 此外，还会加载团队 cmdlet并已连接。 请参阅链接

该脚本仅在 ISE 环境中有效！
