Redeem the Key and Disable Recurring Billing
By redeeming your product key and turning off recurring billing, you can extend your subscription by 12 months without risking automatic charges.
Microsoft allows users to stack subscription time. Redeeming a one-year key will simply add 12 months to your remaining time. It will not replace your current time, and you can stack up to five years in total.
However, to ensure your stored credit card is not charged, you must manually disable the recurring billing feature in your account settings after redemption.
Open your web browser and navigate to setup.office.com or the Microsoft Account Services & Subscriptions page, then sign in with your associated Microsoft account.
Input your 25-character product key when prompted. Follow the on-screen instructions to confirm the 12-month extension to your existing subscription.
Once redeemed, go to 'Services & subscriptions' at the top of your Microsoft account dashboard.
Locate your Microsoft 365 subscription, click on 'Manage', and select 'Turn off recurring billing'. Confirm your choice to prevent any future automatic charges to your saved payment method.
