最近总公司要求Office365需要在所有的邮箱上面打开审计功能。这个功能没法通过图形界面操作,只能通过powershell脚本实现。
微软提供了一个官方的脚本,不过里面有个小bug
https://technet.microsoft.com/en-us/library/dn879651.aspx#step2
当多个用户账户存在相同的alias的时候,他会很奇怪的认为是重名的账户,然后无法修改对应的几个账户,因此不建议直接用get-mailbox | set-mailbox 修改数据,而是手动地for循环处理。
另外还有一个很2的地方是,Office365不能设置默认打开审计,因此所有的新账户都是没有打开的。豆子只能设置一个计划任务,让脚本每天自动执行来修改新账户的设定。
另外,执行完了之后,我希望把修改过的账户都给我发一份邮件通知一下,另外最后windows也给我写个日志,以便日后查看。
下面是完整的脚本
