Working with Active Directory Attributes with multi-values.

It is common for organisations to use or create Active Directory Attributes that may contain multiple different values and when trying to obtain the information using PowerShell you might receive


Which isn’t helpful to man or beast. However, I have been recently working with custom attributes so its time to share my experiences once again. In this post I will be working with information that is located within my personal lab, where I have customattribute10 defined with O365.

# Command
Get-ADUser -Properties * -Filter * | Select-Object samaccountname,customattribute10 | export-csv -Path $env:USERPROFILE\desktop\test1.csv

As you can see that from the above I am not receiving the desired output from Get-ADUser. So lets use a PowerShell string that obtains the required information

Let’s discuss the below string in detail to explain what each part does

@{name=” customattribute10 ”;expression={$_. customattribute10}}

The @ symbol, is the property you are retrieving is an array, which means it contains multiple values. Then you gave the property a name/label (you can name it anything you like). This will be the header of the column in the CSV file

@{name=” customattribute10 ”;

Then you provide an expression; this is the script block where you tell the PowerShell cmdlet what you are trying to fetch. For example; we want to fetch the values for the customattribute10 attribute.

expression={$_. customattribute10}}

So, now we understand the require array to pull the multi-values from lets execute the below command

# Command
Get-ADUser -Filter * -Properties proxyaddresses,customattribute10 | select samaccountname, @{L='customAttribute10'; E={$_.customAttribute10}} | Export-Csv -Path $env:USERPROFILE\desktop\test.csv

Now executing this command you will receive the correct output from the attribute which you desired.
