Remove Old License Files and Reactivate Office

Using the official Microsoft license removal tool resolves conflicts caused by previous Office installations or expired trial licenses on your Mac.

When an old Office license or a trial version is still cached on your Mac, it can prevent newly purchased Microsoft 365 applications from recognizing your new subscription and launching correctly.

1
Download the License Removal Tool

Visit the official Microsoft Support website and download the Office License Removal Tool for Mac.

2
Run the Tool

Open the downloaded .pkg file and follow the on-screen installation prompts to run the license removal process.

3
Restart Your Mac

Once the removal tool finishes, click the Apple menu and select 'Restart' to completely clear any cached licensing data from the system.

4
Sign In and Activate

Launch Word or PowerPoint. When prompted, sign in using the exact Microsoft account email associated with your new Microsoft 365 purchase to activate the apps.

Frequently Asked Questions

Why is my Mac saying no license found even after I purchased Microsoft 365?

This usually happens because older license files or a previous expired trial are still stored on your Mac. Using the Microsoft License Removal Tool will clear these old files so your new subscription can be recognized.

Will uninstalling the Office license delete my Word or PowerPoint documents?

No. Using the license removal tool only resets the activation state of the software. All your personal documents, templates, and files will remain perfectly safe on your Mac.

How do I check for updates on Microsoft Office for Mac if the apps won't open?

If the individual apps won't launch, you can update Office by downloading the latest version of Microsoft AutoUpdate directly from the Microsoft Support website, which will scan and patch your installed apps.
