Powershell ; need help cleaning up results

all, PowerShell n00b here. Enjoying it so far!

I've got a list of users that I need to compare against AD.

I've created a script to search for Get-ADUser Name and EmailAddress for each user, using an array of Divisions as filter.

If AD user is found, write-host user found, show Name, EmailAddress! Easy enough.

If AD use is NOT found, keep looping through all Divisions until the last one, if not found in any Division, print ONLY ONCE "user not found in AD"

I've been playing around with various Do-While, Do-Until loops and If-ElseIf statements but I can't figure out to get it to report only ONCE if not found in any division.

Please help! Thanks, in advance! :)

$Divisions="1","2","3"
$lastd = $Divisions | Select-Object -Last 1

Foreach ($d in $Divisions){
    $aduser = Get-ADUser -Filter "Surname -like '*$lastname' -and GivenName -like '$givenname*'`
     -and Enabled -eq '$True' -and Division -eq '$d'"`
        -SearchBase "OU" -Properties Name, Division, EmailAddress |Select-Object Name,Division,EmailAddress

        if(!$aduser){
            write-host "Usernotfound"
            }
            if($aduser -eq ""){
                write-host "user not found in AD" `n
                }
                else{
                write-host "User Found in $d :" $aduser.Name $aduser.EmailAddress -F Green `n
                }
        }

Here's a sample result when I run script.

USER1 - account will be terminated in 35 days; Last signon activity 2 days ago
****Searching: Active Directory Information
Usernotfound
Usernotfound
Usernotfound
Usernotfound
Usernotfound
Usernotfound
User Found in Division1! Name EmailAddress

USER2 - account will be terminated in 43 days; Last signon activity 4 days ago
****Searching: Active Directory Information
Usernotfound
Usernotfound
Usernotfound
Usernotfound
Usernotfound
Usernotfound
User Found in Division2! Name EmailAddress

Usernotfound
Usernotfound
Usernotfound

I'm sure this is easy stuff for your PS warriors, but I'm dyin here. How can this be done better? Thanks!
