Fix Office Showing One-Time Purchase License After Microsoft 365 Subscription
Question details
The user is unable to use Microsoft Word on a new MacBook Pro because Office incorrectly detects an older one-time purchase license instead of the newly purchased Microsoft 365 subscription.
- Product
- Microsoft 365
- Device & OS
- macOS (MacBook Pro)
- Scenario
- Activating a newly purchased Microsoft 365 subscription on a Mac device.
- Observed behavior
- Office displays an 'action-required' message stating that a one-time purchase license was detected, completely blocking the use of Microsoft Word and other apps.
Ensure you have the login credentials for your active Microsoft 365 account ready, and fully quit all open Microsoft Office applications before proceeding.
Clear Activation Files Using the Office License Removal Tool
Removing the old cached license files forces your Mac to request new activation data directly from your Microsoft 365 subscription.
macOS stores legacy Office activation tokens in hidden system library folders. When transitioning from a one-time purchase to a Microsoft 365 subscription, these files must be cleared using Microsoft's official utility.
Navigate to https://account.microsoft.com/services in your web browser and sign in to confirm your Microsoft 365 subscription is active.
Download Microsoft's official Office License Removal Tool for Mac and open the downloaded .pkg file.
Follow the on-screen prompts to install and run the tool, which will automatically clear all legacy Office license files from your Mac's library.
Launch Microsoft Word. When the activation screen appears, sign in using the email address linked to your new Microsoft 365 subscription.
Reinstall Microsoft Office for Mac
If clearing the license files doesn't resolve the conflict, a clean installation ensures no legacy files interfere with the new subscription.

Frequently Asked Questions
Why is my Mac detecting an old Office license?
When you use a previous version of Office (like Office 2019 or 2021) on your Mac, the licensing files are stored locally. Even after uninstalling the apps, these hidden files remain and take priority over your new cloud-based Microsoft 365 subscription until they are manually removed.
Do I need to uninstall Office before using the License Removal Tool?
No, you do not need to uninstall Microsoft Office first. You can run the License Removal Tool while your current Office applications are still installed. You only need to restart the applications afterward to trigger the new login prompt.
Will removing the license delete my Word documents?
No. The license removal tool only clears activation tokens stored in the system library. It does not touch your personal files, saved documents, emails, or custom templates.
