To unsubscribe from your yearly Microsoft subscription, you can follow these steps:
- Go to the Microsoft 365 admin center.
- If you're using the Simplified view, select Subscriptions.
- If you're using the Dashboard view, go to Billing > Your products.
- Select the subscription that you want to cancel.
- On the subscription details page, in the Billing settings section, under Subscription status, select Cancel subscription.
- If you’re within the grace period during which you can cancel your subscription, select a reason for canceling, provide optional feedback, then select Cancel subscription.
- If you’re outside the grace period, you can only turn off recurring billing, which will prevent future charges but keep your subscription active until it expires.
Make sure to check what type of billing account you have, as the cancellation options may vary depending on that.
