Change device ownership in Microsoft Intune standalone using Microsoft Graph API and Powershell


When enrolling devices into Microsoft Intune using the Company Portal, the devices end up enrolling as personal owned. This can be changed manually on each device directly in the Intune portal after enrollment. Making sure that all devices are company owned refines management and identification, as well as enabling Intune to perform additional management tasks. Also, for additional security, you can configure device restrictions to block enrollment of devices that are not company owned.

But what if we don’t like to do stuff manually and have hundreds or thousands of devices? Automation through Microsoft Graph API and Powershell to the rescue.


  • All of this is done with inspiration from the public available Microsoft Graph API Powershell script samples on GitHub: I suggest that you head over there and dig into the scripts as a first step in this journey.
  • Running anything automated (or manually for that matter) requires an account with proper permissions. A service account with delegated permissions (if not done through a Global Admin). For more information on setting up a service account with proper permissions, see this post:
  • If you really want to automate this to run unattended, you also need some sort of method for authentication. In below script, following Powershell snippet was used to create a credentials.txt file used in combination with a SA with the required permissions:

  • The script itself requires the Azure AD Powershell module. Run Install-Module AzureAD from an elevated Powershell prompt on the computer running the script.

How to

Following is the ManagedDevices_DeviceOwnership_Set.ps1 script from the aforementioned GitHub page with my own modifications. The original script does not have built in authentication and also requires confirmation prior to any action. This is changed in my edition as well as I included a piece that finds all personal owned devices in your tenant and changes the ownertype. The other parts of the script is not my doing.

Copy below script into Powershell ISE and update the authentication region with your own service account / credentials. To fully automate this, this can be run through a scheduled task, but I’m not covering that part here.

Running the script

As mentioned, I’ve removed the requirement for confirmation prior to any action (to be able to run this unattended), so be careful when running the script. It will change the ownertype on ALL personal devices and write the output to the screen. I recommend that you test it on a few devices before running it full blown.

You can limit the result to a few test devices by changing following line:

to something like (and limit on the devicename):

Also, you can of course use the same script to change the ownertype back to personal if that is required. In that case, change the last part of the script to:

The entire script is running towards the Beta API, as the v1.0 API doesn’t have the ownertype data included.

Hope this was helpful 🙂
