   $mailstore = $EXCHANGE_MAILSTORE
   [string]$dn = $person.properties.distinguishedname
      New-Object System.DirectoryServices.DirectoryEntry

   if($domain_person.homeMDB -ne $null)
      #force AD user update

      #print the success
      Write-Host "Success: $dn"
      #print the failure
      Write-Host "Error: $dn"
   #close connections
   $domain_person.dispose | out-null


$domain_query.dispose | out-null
