Get Active Directory Attributes for Users on Legacy Exchange Servers - powershell

Question

I would like to create a CSV file of the users on our Exchange 2003 servers, and include some attributes from their AD account. In particular, I would like to pull certain AD values for the users with RecipientTypeDetails = LegacyMailbox.
I have tried a few different methods for targeting and filtering (ldapfilter, filter, objectAttribute, etc.) these users, with little success. The Exchange 2003 PowerPack for PowerGUI was helpful, but permissions issues and using the Exchange_Mailbox class are not challenges I want to overcome.
I was finally able to create a working script, but it is very slow. The script I've created below is currently working, although it is on track to take about 4+ hours to complete. I'm am looking for suggestions for improving the efficiency of my script or otherwise obtaining this data in a quicker manner. Here is the script:
$ADproperties = 'City','Company','department','Description','DistinguishedName','DisplayName','FirstName','l','LastName','msExchHomeServerName','NTAccountName','ParentContainer','physicaldeliveryofficename','SamAccountName','useraccountcontrol','UserPrincipalName'
get-user -ResultSize Unlimited -ignoredefaultscope -RecipientTypeDetails LegacyMailbox | foreach {Get-QADUser $_.name -DontUseDefaultIncludedProperties -IncludedProperties $ADproperties} | select $ADproperties | epcsv C:\UserListBuilder\exchUsers.csv -notype
Any help you can provide will be greatly appreciated!

I solved this challenge using a script I already created which merges a CSV file with attributes from AD. Basically I used Get-Mailbox to generate a CSV list of all of the Exchange 2003 users, then use that list as input for Get-QADuser to pull the AD attributes I need, and couldn't pull with other cmdlets. The Merge-Object and Export-CSV functions were found from other users on the internet, both very handy functions. Below is a copy of the script:
Function Merge-Object($Base, $Additional)
{
ForEach ($Property in $($Additional | Get-Member -Type Property, NoteProperty))
{
$Base | Add-Member -MemberType NoteProperty -Name $Property.Name -Value $Additional.$($Property.Name) -ErrorAction SilentlyContinue
}
Return $Base
}
Function Export-CSV
{
[CmdletBinding(DefaultParameterSetName='Delimiter',
SupportsShouldProcess=$true, ConfirmImpact='Medium')]
param(

ValueFromPipelineByPropertyName=$true)]
