How to Efficiently Pull UPNs from Office 365 Using PowerShell

PowerShell is a powerful tool that allows you to manage Office 365 accounts programmatically. However, for those new to scripting, tasks like pulling user principal names (UPNs) from a CSV file can seem daunting. In this guide, we’ll guide you through the steps to effectively retrieve UPNs from your Office 365 accounts using a CSV file that contains a list of names.

The Problem Statement

You have a CSV file with a list of names in the following format:

Your goal is to:

Retrieve the UPNs for each user listed in the CSV.

Create a new CSV file that contains only the names and their respective UPNs.

Understand the correct way to format and run your PowerShell commands to ensure that you are extracting data accurately without pulling unnecessary information from Office 365.

Before You Start

Requirements:

Ensure you have access to the PowerShell module for Office 365.

Check that you have the required permissions to run Get-User commands.

Your Current Attempt

Your initial attempt included the following command:

However, this command did not yield the correct results. The key issue is that it did not pull from your local CSV list, causing it to return unexpected results.

The Solution: Correct PowerShell Command

To solve this problem, you can use the following PowerShell script:

Breakdown of the Commands:

Import-Csv
This command reads the CSV file and allows you to access the data as objects in PowerShell.

ForEach-Object
This is a loop that processes each entry in the CSV file.

Get-User -Identity $_.Name.Trim() pulls the user account information associated with each name. The Trim() method is used to remove any leading or trailing spaces, ensuring that the name is formatted correctly.

Select-Object
Here, you specify which fields you want to keep for your output. In this case, you want the Name and UserPrincipalName.

Export-Csv
This command saves the filtered and formatted data into a new CSV file specified by the filepath. The -NoTypeInformation switch is used to omit additional type information that may otherwise clutter your CSV output.

Final Thoughts

Utilizing PowerShell for handling bulk user data can significantly speed up your administrative tasks in Office 365. The above script allows you to streamline the process of pulling UPNs and preparing the data in a clean format.

With the right commands and understanding, you can automate your workflows and minimize potential errors in data handling. Happy scripting!
