Код:

$oufirm = $csv_line.OUF.split(",")
[array]::reverse($oufirm)
$ou_path = $dom.DefaultPartition
$oufirm | Foreach {
	$ou_name = $_
	$ou_parent = $ou_path
	$ou_path = "OU=" + $ou_name + "," + $ou_path
	try{
		$tmp_1 = Get-ADOrganizationalUnit -Identity $ou_path
	}
	catch{
		New-ADOrganizationalUnit -Name $ou_name -ProtectedFromAccidentalDeletion $false -Path $ou_parent
	}
}
