Powershell script help - import-csv return list of UPN and emailaddress

Posted on 2015-01-26

I have a CSV with one column with the header DisplayName.  I want to export a list of UPN's and EmailAddress's for each display name in that column.

I have tried the following:

Import-Module ActiveDirectory
$names = Import-Csv "D:\Users\bhart.difc\desktop\o365 stuff\book4.csv"
foreach ($name in $names) {
$user = Get-ADUser -filter { DisplayName -like $name.DisplayName }


$names = Import-Csv c:\temp\displaynames.txt
foreach ($name in $names) {
$user = Get-ADUser -filter { Name -like $name.DisplayName }

(*altering the column name when required)  

I get errors like:
ERROR: Get-ADUser : Property: 'DisplayName' not found in object of type: 'System.Management.Automation.PSCustomObject'.
get-aduser-displaynames.ps1 (12): ERROR: At Line: 12 char: 9
ERROR: + $user = Get-ADUser -filter { DisplayName -like $name.DisplayName }
ERROR: +         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ERROR:     + CategoryInfo          : InvalidArgument: (:) [Get-ADUser], ArgumentException
ERROR:     + FullyQualifiedErrorId : ActiveDirectoryCmdlet:System.ArgumentException,Microsoft.ActiveDirectory.Management.Commands.GetADUser

This is on a Win8.1 client machine, against 2k8 and 2012 DC's.  Maybe I've just used the wrong keywords googling.  Someone here possibly knows of a simpler terminology to accomplish this.

You're the second one today to post on the same issue.  :)
The problem is with how PS is able to evaluate variables inside of the filter block for Get-ADUser.  The most straight-forward fix is below.
foreach ($name in $names) {
 $display = $name.DisplayName
$user = Get-ADUser -filter { DisplayName -like $display }

You can also use the following script to accomplish this as well.

The command below will out-put the data on the screen
Import-Module ActiveDirectory
$names = Import-Csv "D:\Users\bhart.difc\desktop\o365 stuff\book4.csv"
$names = foreach ($name in $names) {
Get-ADUser -Identity $name.DisplayName | select UserPrincipalName, Mail

Open in new window

The command below will export the info to a csv
Import-Module ActiveDirectory
$names = Import-Csv "D:\Users\bhart.difc\desktop\o365 stuff\book4.csv"
$names = foreach ($name in $names) {
Get-ADUser -Identity $name.DisplayName | select UserPrincipalName, Mail | out-file "c:\UserExport.csv" -append
