PowerShell – Report Inactive AD Users

Recently I’ve start playing a bit with Powershell and here’s a script that I created to audit inactive user accounts in Active Directory. Quickly, the script is searching inactive users in a specific OU as well as all its child OUs.

Then, if there are inactive users, it going to send an email to each OU’s manager containing the following information as well as archiving all the html files into a folder.

Inactive User Report

Noted that in my case, all user’s OUs are within the same OU, such as;


So here’s the script;


#Import AD Module if required
if(@(get-module | where-object {$_.Name -eq “ActiveDirectory”} ).count -eq 0) {import-module ActiveDirectory}

#Define variable

#Report archive folder

#Get Child OUs
$searhOU = Get-ADOrganizationalUnit -SearchBase “ENTER_ROOT_OU_DISTINGUISHEDNAME” -filter * -SearchScope 2


foreach ($OU in $searhOU){

$OUName = $OU.Name

#Define HTML format
$head = @”
body { background-color:#FAFAFA;font-family:Arial;font-size:12pt; }
td, th { border:1px solid black;border-collapse:collapse; }
th { color:white;background-color:black; }
table, tr, td, th { padding: 2px; margin: 0px }
tr:nth-child(odd) {background-color: lightgray}
table { margin-left:50px; }
<H2>This report list inactive users in $OUName OU<BR></H2>

$users = Search-ADAccount -SearchBase $OU.DistinguishedName -accountinactive -TimeSpan $lastDays -usersonly -SearchScope 1 `

if ($users -ne $NULL){

$fragments += $users | ConvertTo-HTML -Fragment
$filePath = Get-Date -uformat ($folderPath + $OUName + “_%d%m%Y.htm”)

ConvertTo-HTML -Head $head -Body $fragments -PostContent “<br><br><i>report generated: $(Get-Date)</i>” `

$subject = “Report – Inactive user”
$body = (get-content $filePath ) | out-string

$obj = $NULL
$fragments = $NULL
$users = $NULL
