Fix Office 2019 for Mac Lost Activation After an Update
Question details
Office 2019 for Mac incorrectly requests a Microsoft 365 account for activation instead of recognizing its perpetual license after a software update.
- Product
- Microsoft Office 2019 for Mac
- Device & OS
- macOS
- Scenario
- Launching Office 2019 applications after completing a recent macOS system or Microsoft software update.
- Observed behavior
- The existing perpetual Office 2019 license is no longer recognized, and the software continually prompts the user to activate using a Microsoft 365 subscription account.
Ensure you have the login credentials for the exact Microsoft account you originally used to purchase or register your Office 2019 for Mac license.
Verify Account License and Use the License Removal Tool
Clear out conflicting or corrupted license files on your Mac to force Office to correctly recognize your Office 2019 perpetual license.
Software updates can sometimes cause Office for Mac to read outdated or conflicting license caches, leading it to mistakenly assume you are on a Microsoft 365 subscription. Removing these hidden files resets the activation state.

Click the Apple logo in the top left corner and select 'Restart' to ensure all background Microsoft processes are completely closed and reset.

Frequently Asked Questions
Why is my Office 2019 asking for a Microsoft 365 subscription?
After a software update, Office may default to checking for a Microsoft 365 subscription if it encounters a conflicting license file on your Mac, or if you are accidentally signed in with a different Microsoft account.
Will the License Removal Tool delete my Word and Excel documents?
No, the Microsoft Office License Removal Tool only removes hidden activation and license files from your system. It will not delete, move, or modify any of your personal documents, spreadsheets, or presentations.
How do I check if my Office 2019 license is still valid?
Navigate to account.microsoft.com/services in your web browser and sign in with your Microsoft account. Look under the 'Products & Services' section to confirm your Office 2019 perpetual license is permanently tied to your account.
