If you’re troubleshooting Office and would like to remove the license files on your Mac, you can use the license removal tool. This will completely remove all licenses for Microsoft 365 for Mac.
Important: Before using the tool, make sure you have the correct account info and password associated with your purchase of Office available for when you reactivate.
This tool can also help if you’ve subscribed to Microsoft 365 but previously had a one-time purchase of Microsoft 365 for Mac on your computer, and aren’t seeing certain subscription features. This can be due to your copy of Office still using the license of your one-time purchase and not your subscription.
