Contact Microsoft Support to Transfer Your Office License
Since the previous computer was factory-reset before Office could be uninstalled, you must contact Microsoft Support to manually release and transfer the license to your new laptop.
Microsoft Office Professional Plus 2021 is typically a one-device license. If the software is not deactivated before a PC is wiped, Microsoft's activation servers still register the license as active on the old hardware.
Open your web browser and navigate to the official Microsoft Support chat page at http://support.office.com/home/chat.
In the search box, type 'I need help with my Office license' and click on the 'Get Help' button. Scroll down to the bottom of the page and select 'Contact Support'.
Choose 'Microsoft 365 and Office' as the product. For the category, select 'Manage my subscription', and then click 'Confirm'.
Click on 'Chat with a support agent in your web browser', confirm your email address if prompted, and click 'Start Chat'. Explain that your old PC was factory-reset and ask them to release the license for your new laptop.

Frequently Asked Questions
