I have a CSV file with the following columns
"EMPLOYEE_NUMBER","UNIQUE_ID","FIRST_NAME","LAST_NAME","SAMACCOUNT"

I want to test whether or not the sAMAccount is in AD or not. I want to capture the status in a new column called "STATUS" (Y or N) so my output file should look like this:
"EMPLOYEE_NUMBER","UNIQUE_ID","FIRST_NAME","LAST_NAME","SAMACCOUNT","STATUS"

I'm having trouble reusing a piece of code that someone gave me for a different thing..but thought I could use it for this task.
Function CheckADUser($filename, $output)
{
    $csv = Get-Content -Path $filename

    # This adds the column...but I'm having trouble adding the result of each iteration to the file
    $csv[0] += ",STATUS"
    $b
    foreach($line in $csv)
    {

        $user = Get-QADUser -Name $line.SAMACCOUNT
        if ($user){
		
# I dont know how to add the "Y" under the STATUS column		
$b += $line.EMPLOYEE_NUMBER + "," + $line.UNIQUE_ID + "," + $line.FIRST_NAME + "," + $line.LAST_NAME + "," + $line.SAMACCOUNT  + "`n"
		}
		else{
# I dont know how to add the "N" under the STATUS column	
		$b += $line.EMPLOYEE_NUMBER + "," + $line.UNIQUE_ID + "," + $line.FIRST_NAME + "," + $line.LAST_NAME + "," + $line.SAMACCOUNT + "`n"
		}
    }
    Out-File -FilePath $output -Encoding ASCII -InputObject $b
}

CheckADUser "C:\scripts\output\source.csv" "C:\scripts\Output\results.csv"

Please try this.
Function CheckADUser($filename, $output) {
    Import-Csv $filename | ForEach-Object {
        $_ | Add-Member -PassThru -MemberType noteproperty -Value (
            if(Get-QADUser -samaccountName $line.SAMACCOUNT){"Y"}else{"N"}
        )
    } | Export-Csv -Path $output -Encoding ASCII -NoTypeInformation
}

Sorry, this one:
Function CheckADUser($filename, $output) {
    Import-Csv $filename | ForEach-Object {
        $_ | ForEach-Object {Add-Member -InputObject $_ -PassThru -MemberType noteproperty -Value @(
                if(Get-QADUser -samaccountName $_.SAMACCOUNT){"Y"}else{"N"}
            )}
    } | Export-Csv -Path $output -Encoding ASCII -NoTypeInformation
}

Awfully sorry, but this is really the good one:
Function CheckADUser($filename, $output) {
    Import-Csv $filename | ForEach-Object {
        $_ | ForEach-Object {Add-Member -name Status -InputObject $_ -PassThru -MemberType noteproperty -Value $(
                if(Get-QADUser -samaccountName $_.SAMACCOUNT){"Y"}else{"N"}
            )}
    } | Export-Csv -Path $output -Encoding ASCII -NoTypeInformation
}
