Verify Account and Use the License Removal Tool
Clearing corrupted or incorrect license files using Microsoft's official removal tool is the most reliable way to fix the activation loop on macOS.
Often, your Mac retains outdated or incorrect license files from a previous Office installation. This tool securely wipes those hidden files so you can start with a clean activation state.
Navigate to account.microsoft.com/services in your web browser and sign in to confirm that your Office Home and Business 2021 license is actively linked to your account.
Search for and download the official 'Microsoft Office License Removal Tool for Mac' from the Microsoft Support website.
Open the downloaded .pkg file and follow the on-screen installation prompts to remove the existing license files from your Mac.
Restart your Mac, open Microsoft Word, and click 'Sign In' when prompted. Enter the credentials of the account verified in step one to properly activate the software.
Perform a Clean Reinstallation of Office
If clearing the license files fails to resolve the issue, reinstalling the entire Office suite can fix underlying application corruption.
Switch to WPS Office for Mac for a Hassle-Free Experience
If persistent Microsoft Office activation loops are disrupting your workflow, consider switching to WPS Office. It provides a lightweight, fully compatible, and free alternative that works seamlessly on Mac without complex activation hurdles.
- 1. Download WPS Office: Visit the official WPS website and click the free download button for the macOS version.
- 2. Install on your Mac: Open the downloaded package and drag the WPS Office icon into your Applications folder.

Frequently Asked Questions
Why does my Mac say no license is found for Office 2021?
This commonly occurs if you are signed in with a different Microsoft account than the one used to purchase the software, or if the local license configuration files on your Mac have become corrupted.
Will the license removal tool delete my Word documents or Excel spreadsheets?
No, the Microsoft Office License Removal Tool exclusively targets hidden system files related to software activation. Your personal files and application preferences remain completely safe.
What should I do if removing the license and reinstalling still doesn't work?
If both troubleshooting methods fail, the issue may be on Microsoft's server end or related to a blocked product key. You will need to contact Microsoft Support directly to verify the status of your Office 2021 license.
