Finding AD Distro Group samaccountname with email address

Question

I need to move a few hundred AD distro groups to a new OU. I was given their email address only, and wanted to make a script to move them based on samaccountname. I am wondering why the below does not return anything, if I do the groups one-off filtering for email address it works, but foreach returns nothing.

The "groups.txt" listed below is just a list of email addresses.

gc groups.txt | % {
  Get-ADGroup -Filter {mail -eq "$_"}| Select-Object -ExpandProperty SamAccountName
}

Answer 1

Remove the quotes you have around $_ .

gc groups.txt | % {
  Get-ADGroup -Filter {mail -eq $_}| Select-Object -ExpandProperty SamAccountName
}

In your posted filter script block the variable is quoted. Since it is a script block, PowerShell doesn't do any processing first and the ActiveDirectory module expects a variable not surrounded in quotes. That would look for Mail that is literally "$_" and not the email address value of the variable.

Answer 2

取消$_的“”

gc groups.txt | %{ Get-ADGroup -Filter {mail -eq "$_"} | select -expandproperty samaccountname}
