- Scenario

Ensure you have the exact login credentials for the Microsoft account associated with your newly purchased Microsoft 365 Family subscription.
Switch Your Account Without Reinstalling
You do not need to uninstall or reinstall your Office applications. Simply sign in with the account linked to the new subscription to activate the license.
Microsoft Office applications verify licenses based on the account currently signed in. By switching the active account inside the software, the system will automatically recognize the new Microsoft 365 Family license.
Launch any existing Office application on your computer, such as Word, Excel, or PowerPoint.
Click on 'File' in the top-left corner of the application window, then select 'Account' (or 'Office Account' depending on your version) from the bottom of the left sidebar.
Under the 'User Information' section, click the 'Sign out' link to remove the Microsoft account associated with the expiring subscription.
Click 'Sign in' and enter the email address and password for the Microsoft account associated with the new Microsoft 365 Family subscription.
Close the Office application entirely and reopen it to ensure the new license takes effect and the subscription warning disappears.

Frequently Asked Questions
Will I lose my files if my old Microsoft 365 subscription expires?
No, files stored locally on your device will remain completely safe and accessible. However, if you have files stored on OneDrive and your new subscription doesn't cover the same storage capacity, those files may become read-only until storage is freed up.
Can I share my new Microsoft 365 Family subscription right away?
Yes, once your new Microsoft 365 Family subscription is active on your account, you can immediately share it with up to 5 other people through your Microsoft account dashboard online.
What happens if I enter the new product key before the old one expires?
If you are renewing the exact same subscription tier, the remaining time is usually added to your new term. If you are upgrading from Personal to Family, the new subscription takes over immediately and remaining Personal time is converted to Family time based on Microsoft's conversion ratios.
