Download the official Microsoft Office License Removal Tool for Mac. Open the downloaded .pkg file and follow the on-screen instructions to clear the existing license files.
Click the Apple menu in the top-left corner of your screen and select 'Restart' to ensure all background licensing services are fully reset.
Open any Office application, such as Microsoft Word. When prompted to activate, sign in with your verified Microsoft account to complete the setup.

Frequently Asked Questions
Why does the 'Unable to connect to licensing helper' error happen on a Mac?
This error occurs when the background service responsible for verifying your Microsoft Office license (the licensing helper) fails to start, crashes, or is blocked by corrupted cached license files on your Mac.
Will running the Microsoft license removal tool delete my Word or Excel files?
No. The license removal tool only clears activation data and cached account credentials from your Mac's keychain. It does not touch, delete, or modify any of your personal documents, spreadsheets, or presentations.
What should I do if the license removal tool does not fix the activation error?
If the tool doesn't resolve the issue, ensure your Mac's macOS is fully updated, temporarily disable any active VPNs or firewall software, and reach out to Microsoft Support for advanced diagnostics on the licensing helper service.
