The user needs to reactivate or transfer a preinstalled Office Home and Student 2021 license on a second-hand laptop.

How to Reactivate Office Home and Student 2021 on a Used Laptop

Product: Microsoft Office Home and Student 2021
Device & OS: not provided
Scenario: The user acquired a used laptop that originally included Office 2021, but a factory reset removed the activation.
Observed behavior: The preinstalled Office entitlement did not transfer to the new owner's Microsoft account and remains tied to the original owner's account.

Before you start

Before attempting to transfer the license, ensure you have a way to contact the laptop's original owner, as their authorization is strictly required by Microsoft Support.

Solution 1Recommended

Transfer License via Microsoft Support (EEA Regions)

If you are located in the European Economic Area (EEA), you can legally transfer the license with the original owner's assistance.

Microsoft Office 2021 licenses are permanently linked to the original Microsoft account used during the initial setup. Performing a factory reset wipes local data but does not unlink this digital entitlement from the cloud.

However, if both parties reside in the European Economic Area (EEA), European laws permit the transfer of this software license to a new owner.

Contact the previous owner

Reach out to the person who originally owned the laptop and initially activated the Office 2021 software.

Initiate a support request

Navigate to the Microsoft Support Contact page and have the original owner sign in with their Microsoft account.

Request the official transfer

Instruct the original owner to open a ticket with Microsoft Support explicitly requesting to transfer the Office 2021 digital entitlement to your specific Microsoft email address.

Sign in to activate

Once Microsoft Support confirms the transfer is complete, open Word or Excel on the used laptop and click 'Sign In' using your own Microsoft account credentials.

Transfer License via Microsoft Support (EEA Regions)

Regional Limitations: Outside of the EEA, Microsoft generally does not allow the transfer of preinstalled OEM Office licenses to a different user, meaning the license cannot be officially moved.

Solution 2

Purchase a New License or Subscription

If a transfer is not permitted in your region or the original owner is unavailable, you must acquire a new license.

Frequently Asked Questions

Why didn't the factory reset transfer the Office license automatically?

Microsoft Office 2021 digital licenses are permanently tied to a user's cloud-based Microsoft account, not the physical hardware of the laptop. A factory reset only wipes the local hard drive but does not unlink the online digital entitlement.

Can I use the product key on the bottom of the laptop to reactivate Office?

Modern laptops generally use digital licenses linked to Microsoft accounts rather than physical product keys for Office. Even if a sticker exists, the key was likely consumed and permanently attached to the original owner's account during the first setup.

Can I just log in with the original owner's Microsoft account?

While technically possible if they willingly provide their credentials, it is highly discouraged due to severe privacy and security risks. Using their account gives you access to their personal emails, OneDrive files, and compromises their account security.

Is it possible to transfer an Office license in the US or UK?

Typically, Microsoft's retail and OEM license agreements outside of the European Economic Area (EEA) do not allow the transfer of an Office license to another person once it has been linked to the initial Microsoft account.
