Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Because account recovery has already failed, contact Microsoft Billing Support to investigate the charge using the transaction details and stop the subscription; a public forum cannot access billing records or identify the associated account.^1^
1. Ask Billing Support to trace the subscription
- Open Contact Microsoft Support.
- Sign in with any Microsoft account you can access; it does not have to be the unknown purchasing account.
- Enter Microsoft 365 unknown recurring charge and select Get Help.
- If the automated guidance does not resolve it, select Contact Support and request chat or a callback.^2^
- Explain that:
- The charge is recurring.
- You no longer know the purchasing Microsoft account.
- Account recovery has already been unsuccessful.
- You need the subscription investigated, future renewal stopped, and refund eligibility reviewed.
Have the following available because they may help Support locate and verify the transaction:
- Exact charge amount, currency, and date
- Bank-statement charge description
- Last four digits of the payment card
- Transaction/reference number
- Approximate original purchase date
- Any old email addresses or Microsoft accounts that might have been used
Do not post those details here. Billing Support may investigate after identity or payment verification, but security rules may limit what account information can be disclosed.
You can also use Manage your payments → Investigate from any accessible Microsoft account. Microsoft identifies recurring billing and purchases by family members as possible explanations for an unrecognized charge.^2^
2. Special case: subscription purchased in Germany
If the subscription was purchased in Germany, Microsoft provides a cancellation process that does not require signing in. Use Cancel a Microsoft subscription acquired in Germany and supply the requested purchase information.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Unable to cancel your Microsoft subscription | Microsoft Support")
3. Cancel once the purchasing account is accessible
For a subscription bought directly from Microsoft:
- Open the Microsoft 365 subscription page: https://account.microsoft.com/services/microsoft365
- Sign in with the account that purchased it.
- Select Cancel subscription or Upgrade or Cancel.
- Review the cancellation page and select I don’t want my subscription.
If the page displays Turn on recurring billing, auto-renewal is already disabled and the subscription will expire on the displayed date.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Cancel a Microsoft 365 subscription | Microsoft Support")
If the charge came through Apple, Google Play, Amazon, or another retailer, cancellation and refund must be handled by that provider rather than Microsoft.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Unable to cancel your Microsoft subscription | Microsoft Support")
4. Refund eligibility
For subscriptions purchased directly from Microsoft:
- Refund eligibility is determined during cancellation; cancellation does not always produce a refund.
- The most recent recurring charge is generally refundable when cancellation occurs within 30 days after payment, limited to one refund per Microsoft account and subscription product.
- Additional prorated-refund rights vary by country/region, subscription type, and applicable law.
- If no refund is issued, Microsoft 365 access normally continues through the current billing period.[^5^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
If the transaction is not yours and payment information may have been compromised, contact the bank or card issuer as well. Microsoft advises reporting the card as compromised rather than only disputing one charge, because a dispute alone may not prevent additional charges.^2^
