Have 2 Microsoft accounts in error. Pd full year & now notified being billed in May for other already cancelling second account.

Being billed on two Microsoft accounts usually means there are two separate subscriptions, often under different email addresses (for example, one with Outlook.com and one with Gmail.com), and cancelling one does not affect the other.

To stay with only one subscription and stop being billed for the other:

1. Identify which account/subscription to keep
   • Sign in to https://account.live.com with the Microsoft account that has the subscription already paid for the full year.
   • Go to Subscriptions and confirm the active Microsoft 365 subscription and its expiry date.
2. Cancel the extra subscription
   • Sign out, then sign in with the other Microsoft account (the one that should not keep the subscription).
   • Go to Subscriptions again and select Manage for the Microsoft 365 plan that is being billed on this second account.
   • Use the Cancel subscription or Turn off recurring billing option so future charges stop. Canceling the subscription does not delete the Microsoft account; the account remains, only the recurring billing stops.
3. If charges still appear or cancellation is not possible
   • Verify that the correct Microsoft account is being used when checking subscriptions, as using the wrong account is a common cause of unexpected charges.
   • If a charge appears after cancellation, it may be because cancellation was too close to the billing date; check the subscription end date under Services & subscriptions.
   • If there is money owing or an expired card on the extra subscription, pay any overdue amount or update the payment method before cancellation, as overdue balances can block cancellation.
4. If there are also charges from a third party (for example, Amazon)
   • If one of the subscriptions was purchased through a retailer such as Amazon, that subscription must be managed and cancelled with that retailer directly, as shown in the example where Amazon cancelled and refunded the last charge.
5. If still being charged twice or unsure which account is charging
   • Review order history for each Microsoft account to see which one is generating the charges.
   • Use Payment options → Investigate on the Microsoft account dashboard to check if multiple accounts are using the same card.

For complex billing situations (for example, difficulty cancelling, unclear duplicate charges, or needing a refund), contact Microsoft Billing Support so they can securely review both accounts and stop the extra billing.
