Question

我发现这个脚本可以从单个用户中删除组，但我害怕在我的环境中尝试它：问题 - 是否有在线测试实验室，我可以运行这些脚本而不会破坏我自己的环境？如果我想从用户中删除组，那么拥有更多脚本/ powershell知识的人可以验证这是否可以安全运行？我被指示在它之后运行带有参数的脚本，即c：/sripts/removegroups.ps1 username @ domain“是正确的吗？

$user = $args[0] if (!$args[0]) {

} $mailbox=get-mailbox $user

$dgs= Get-DistributionGroup

foreach($dg in $dgs){

$DGMs = Get-DistributionGroupMember -identity $dg.Identity
foreach ($dgm in $DGMs){
if ($dgm.name -eq $mailbox.name){

    write-host 'User Found In Group' $dg.identity
      Remove-DistributionGroupMember $dg.Name -Member $user
}
}
}

Answer 1

您可以在Remove-DistributionGroupMember命令上使用 whatif 开关

$user = $args[0] if (!$args[0]) {

} $mailbox=get-mailbox $user

$dgs= Get-DistributionGroup

foreach($dg in $dgs){

$DGMs = Get-DistributionGroupMember -identity $dg.Identity
foreach ($dgm in $DGMs){
if ($dgm.name -eq $mailbox.name){

   write-host 'User Found In Group' $dg.identity
      Remove-DistributionGroupMember $dg.Name -Member $user -Whatif
}
}
}

WhatIf开关指示命令模拟对对象执行的操作。通过使用WhatIf开关，您可以查看将发生的更改，而无需应用任何这些更改。您不必使用WhatIf开关指定值。

将$WhatIfPreference设置为$true，脚本中的所有命令都应显示在真实运行时会发生什么。这比稍微修改脚本命令（稍微）容易一些。

Answer 3

看起来像这样吗？

$WhatIfPreference = $true 
$user = $args[0] if (!$args[0]) {

} $mailbox=get-mailbox $user

$dgs= Get-DistributionGroup

foreach($dg in $dgs){

$DGMs = Get-DistributionGroupMember -identity $dg.Identity
foreach ($dgm in $DGMs){
if ($dgm.name -eq $mailbox.name){

write-host 'User Found In Group' $dg.identity
  Remove-DistributionGroupMember $dg.Name -Member $user
}
}
}

WARNING: By default, only the first 1000 items are returned. Use the ResultSize
 parameter to specify the number of items returned. To return all items,
specify "-ResultSize Unlimited". Be aware that, depending on the actual number
of items, returning all items can take a long time and consume a large amount
of memory. Also, we don't recommend storing the results in a variable. Instead,
 pipe the results to another task or script to perform batch changes.
