Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Glenna Fernandes
I understand that you previously had Office Home & Student 2016 installed on your laptop, but it has now been replaced by Microsoft 365, which you do not have a subscription for.
If your Office 2016 license is still associated with your Microsoft account, you should be able to reinstall and reactivate it. Here is what you can do:
- Sign in to your Microsoft account Services & subscriptions page using the account originally used to activate Office 2016.
- Check whether Office Home & Student 2016 appears under Products you’ve purchased.
- If listed, uninstall the current Microsoft 365 installation from Settings > Apps > Installed apps, then select Install beside Office 2016 on the account page.
- Open Word or Excel and sign in with the same Microsoft account to activate it.
Please note that support and security updates for Office 2016 ended on October 14, 2025. The software may continue to work, but using a supported Office version is recommended for security.
I hope this helps you restore your Office installation.
