Parsing CSV Data to another CSV based on Samaccountmatch - powershell

Question

I have 2 csv's, 1 from exchange and 1 from AD. I am querying for samaccountname, emailaddress, enabled in AD. I am querying for samaccountname, primarysmtpaddress where recipienttype is 'usermailbox'.
After these are compared it spits out a 3rd csv based on the mismatches it finds. I need to parse the primarysmtpaddress from the exchange csv to the next column and only the addresses based on the samaccountname.
Also, any suggestions are welcome. First time here :)
AD Script
$ErrorActionPreference = 'Continue'
$SamAccountPath = "Path\get_adusers.csv"

Try{
if (Test-Path $Folder)
{}
else

I rewrote it and found this solution:
#Globals for warnings/error action
$WarningPreference = 'SilentlyContinue'
$ErrorActionPreference = 'SilentlyContinue'
#import activedirectory cmdlets
import-module -name activedirectory
#Collects Exchange cmdlets into PSSession and imports it into the current session.
$exchangeuser = "user"
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionURI http://exchange/powershell/ -Authentication kerberos
import-PSSession $session -AllowClobber
#Declare paths
$MismatchPath = "Path\AD_EX_Mismatches.csv"
$MismatchPathE = "Path\AD_EX_MismatchesE.csv"
#Creates empty array
$errorstatus = #()
#Gets all mailboxes that are 'UserMailboxes' and not 'Contacts' it then pipes sam and psmtp to get-aduser. The #{n="";e={}} is creating a table and running an expression or cmdlet.
$gUser = Get-Mailbox -ResultSize Unlimited | Where-Object {$_.recipienttype -eq "UserMailbox"} | select samaccountname, primarysmtpaddress,#{n="ADEmail";e = {Get-ADuser $_.samaccountname -Properties emailaddress | select -ExpandProperty emailaddress}},#{n="Error";e={$errorstatus}}
#Foreach object (Samaccountname,primarysmtpaddress,emailaddress,error). Check if the conditions are met, if so, output the $gUser.Error to the CSV
$gUser | ForEach-Object {
if($_.ADEmail -ne $_.PrimarySmtpAddress){
$_.Error = "Mismatch"
}
if($_.ADEmail -eq ' '){
$_.Error = "Corrupted"
}
}
$gUser | Export-Csv $MismatchPath -NoTypeInformation -Force | Out-Null
#Finds blanks in the csv and re-exports it to a new path.
Import-Csv $MismatchPath | Where-Object {$_.samaccountname -and $_.primarysmtpaddress -and $_.error -notlike ""} | select * | export-csv $MismatchPathE -NoTypeInformation -Force
#Finds EX session and removes it
Get-PSSession | Remove-PSSession
#Send email with args
Send-MailMessage -SmtpServer "mailserver" -Attachments $MismatchPathE -From "emailaddress" -to "email address" -Subject "Mismatch Report" -Body "Attached is a report of mismatches of email addresses between AD and Exchange."
