Remove Office 365 license from a Computer with PowerShell

One of my users got a notice in Office 2016 that he needed to reactivate his Office 365 subscription. After clicking reactivated a warning came up that “there was a problem with your Office 365 subscription, and we need your help to fix it“. The problem was that the registered license belonged to a user that was no longer working at our company and that license was revoked. So how can we remove the Office 365 license from this computer?

Finding out the real problem

First I wanted to know why the license was not working anymore. In Office 365 the licenses are assigned to a user. When you remove the user and revoke the license then within 90-days the installed Office 2016 will no longer work. During this grace period, you can buy / re-assign the license to the new user.

Now to check if the computer in question is licensed by this user you can log in to Office 365 and goto the My Account page: https://portal.office.com/account/. Here you see an overview of the devices on which the license is used.

Another way to check who’s license is used for the Office Installation is to open Word or Outlook and go the File > Office Account

The output of the command looks like below. There could be more than one key listed, so look for a license with a REMAINING GRACE or Grace Periode Expired line just above the last 5 characters of the product key.

Take a note of the 5 last characters of the product key that we need to remove.
