Hi, try this script:<br />

<pre><code class="code-1 nolinks" id="code-20-38177063-1"><span>Import-Module ActiveDirectory</span>
<span>Get-ADUser -Filter {SurName -eq &quot;Smith&quot;} | ft GivenName,Surname,UserPrincipalName</span>
</code></pre>
</div>


<div>
Is it possible to have the script check on it's own for any duplicates without me specifying a specific SurName?
</div>

You can try the below logic. This works in Exchange Management shell. if you are using windows powershell you can use the same logic with different commands.<br />
<br />
$Users = Get-User<br />
foreach($user in $Users){<br />
$Surname = $user.lastname<br />
foreach($dupuser in $Users){<br />
if($Surname -eq $dupuser.lastname){<br />
Write-Host $user.displayname,$user.Fi<wbr />rstName,$u<wbr />ser.samacc<wbr />ountname<br />
}<br />
}<br />
}
</div>
