How to Restore Microsoft 365 After a Laptop Repair
Question details
The user needs to recover their legitimate Microsoft 365 subscription after a repair shop installed a different, unauthorized, or trial version of Microsoft Office.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- A laptop was recently repaired, and the repair technician installed an incorrect version of Microsoft Office.
- Observed behavior
- The currently installed Office version displays the error message 'This copy of Microsoft Office is not activated'.
Ensure you have the email address and password for the exact Microsoft account associated with your active Microsoft 365 Personal, Family, or Business subscription.
Uninstall the Incorrect Office Version and Reinstall Microsoft 365
Remove the unauthorized or trial version installed by the repair shop and download your official Microsoft 365 setup directly from your account.
Repair shops often install generic trial versions of Office to test the system. Since these installations do not match your personal Microsoft 365 account license, they will fail to activate. You must completely remove this version before reinstalling your own.
Open the Windows Control Panel, go to 'Programs and Features', find the Microsoft Office version installed by the repair shop in the list, right-click it, and select 'Uninstall'.
Open your web browser, navigate to https://account.microsoft.com/services, and sign in with the Microsoft account linked to your Microsoft 365 subscription.
Locate your active Microsoft 365 subscription on the dashboard, click the 'Install' button, and follow the on-screen instructions to download the installer.
Run the downloaded setup file. Once the installation is complete, open Word or Excel and sign in with your Microsoft account when prompted to activate the software.

Verify and Reassign Business Licenses
If you are using a work or school account, you may need to confirm your license assignment with your organization's IT department.
Run the Microsoft Support and Recovery Assistant
Use the official Microsoft troubleshooting tool to automatically detect and fix residual activation errors from the repair shop's installation.

Frequently Asked Questions
Why does my repaired laptop say Office is not activated?
Repair shops often install a generic trial or a different volume license version of Office to test the system after a repair. Since it doesn't match your personal Microsoft 365 account, it fails to activate and displays an error.
Do I have to pay again if the repair shop deleted my Microsoft 365?
No. Your Microsoft 365 subscription is tied to your Microsoft account, not the physical laptop. You can reinstall and activate it for free by signing into your account's Services and Subscriptions page.
How do I know which Microsoft account is linked to my subscription?
You can check by searching your email inboxes for billing receipts from Microsoft, or by attempting to sign in at account.microsoft.com to see if an active subscription is listed under your services.
