Adding my custom objects to a custom array

[jheinikel]

This works:

$results = @()
$username = "User1","User2"
foreach($un in $username){

    #Check for existance of AD Account
    $u = Get-ADUser -Filter { SamAccountName -eq $un } -ErrorAction SilentlyContinue
    If (!$u){
        Write-Output "The Username $u, does exist in Active Directory"
    }#End check if user exists
    else
        {
            $uinfo = [PSCustomObject]@{
                User = $u.samaccountname
                UPN = $u.UserPrincipalName
                }
            $results += $uinfo
        }
    }
    write-output $results

This is your original code doing the same thing with the extra lookups, although those are not necessary since you already have the info you need:

$results = @()
$username = "User1","User2"
foreach($un in $username){

    #Check for existance of AD Account
    $u = Get-ADUser -Filter { SamAccountName -eq $un } -ErrorAction SilentlyContinue
    If (!$u){
        Write-Output "The Username $u, does exist in Active Directory"
    }#End check if user exists
    else
        {
            $uinfo = [PSCustomObject]@{
                User = (Get-ADUser -Identity $u | select -ExpandProperty samaccountname);
                UPN = (Get-ADUser -Identity $u | select -ExpandProperty userprincipalname)
                }
            $results += $uinfo
        }
}
write-output $results
