Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
If the subscription was bought with a Microsoft account that uses a Gmail address, the Gmail address itself does not need to still be active. What matters is signing in to the same Microsoft account that purchased the subscription.
- Go to the Microsoft account subscriptions page and sign in with the same Microsoft account used for the purchase.
- Find the Microsoft 365 subscription.
- Select Cancel subscription. It might appear as Upgrade or Cancel.
- Review the cancellation page, then select I don't want my subscription to confirm.
If Cancel subscription is not shown:
- If Turn on recurring billing appears instead, the subscription is already set to expire and no further action is required.
- Make sure the correct Microsoft personal account is being used.
- If the subscription was purchased through Apple App Store, Google Play, Amazon, or another retailer, cancellation must be done with that provider directly. Microsoft cannot cancel or refund those subscriptions.
If access to the old Microsoft account is no longer possible and the subscription cannot be reached, the accepted guidance in similar cases is to cancel the recurring payment with the payment provider, such as PayPal, the card provider, or the bank.
