Automated Office 365 Licensing v1.1

Update 2019-06-16

I recently learned that Office 365 licensing can be managed via Azure Active Directory’s group based licensing feature and I have since switched to using this and have retired this script. I’ll leave this post and the script itself available here, on the Microsoft TechNet Gallery and GitHub, but I’ll not be developing the script any further. For more information on Azure Active Directory group-based licensing please check out Microsoft’s documentation here and here to start with.

PowerShell script to assign Office 365 license to users in an Active Directory OU structure.

Features and Requirements

This utility will assign a configurable Office 365 license to Active Directory user accounts within an OU or descending OUs. All options are added via command line switches. Options include:

  • The Office 365 Global Admin user and password to use.
  • The Office 365 license and usage location to assign.
  • Organisation Unit which contains to users to license.
  • The directory to output a log file to.
  • An optional email address to send the log file to.
  • This utility has been tested running on Windows Server 2016. This utility requires the MSOnline and Active Directory PowerShell modules to be installed.

The script has been tested on Windows 10, Windows Server 2016 (Datacenter and Core installations) and Windows Server 2012 R2 (Datacenter and Core Installations) with PowerShell 5.0.

Generating A Password File

The password used for SMTP server authentication must be in an encrypted text file. To generate the password file, run the following command in PowerShell, on the computer that is going to run the script and logged in with the user that will be running the script. When you run the command you will be prompted for a username and password. Enter the username and password you want to use to authenticate to your SMTP server.

Please note: This is only required if you need to authenticate to the SMTP server when send the log via e-mail.
