Why would you want to remove Office License?

Updated? Perhaps, for upgrades reasons. The Support for Office 2019 for Mac ended on October 10, 2023. Perhaps, you have an alternative reason like mine below.

I recently had to remove Office from my MacBook due to licensing issues. Remember, this copy of Office is available as a one-time purchase and it is associated with your Mac.

As you see in the field it belongs to, my ex-company was listed as shown in the image below. There was a real need to disassociate my device from this license file. A similar issue was reported in the Microsoft Answer Forum. Therefore, I will be showing you the steps to remove Office license files on your macOS.

As you can see below, you will be able to use your personal email for any Office related operation and as such may be difficult for you to spot the licensing inconsistency.

Note: Even when you reinstall office with a new subscription from your school, work, or personal account, this will not replace the license or the account it belongs to.

How then can you dissociate a license file from your Mac? Please download and run the license removal tool to remove Office license file from your Mac?
