Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Because four replacement cards have not stopped the charges, ask your bank’s fraud team to block Microsoft’s recurring/card-on-file payment authority and merchant token—not merely replace the physical card—and open formal disputes for every unauthorized transaction.
What to tell the bank
Use wording such as:
These are unauthorized recurring or card-on-file transactions. Replacing my card four times has not stopped them. Please check whether an account-updater service or merchant token is carrying the payments onto each replacement card. Block the Microsoft merchant token and recurring-payment authority, opt this card out of updater sharing for this merchant if possible, and open disputes for every transaction.
Card-network account-updater services can provide participating merchants with updated card credentials for recurring and credential-on-file payments after a card is replaced.^1^
Also ask the bank to:
- Give you the exact merchant descriptor, transaction/reference IDs, dates, and amounts.
- Confirm whether each payment is marked recurring, card on file, or token-based.
- Place a merchant-level stop against future transactions matching that descriptor.
- Escalate the matter to its card-network fraud or disputes team if the first representative can only offer another replacement card.
Microsoft specifically advises telling the payment provider that the card details have been compromised; disputing charges alone does not necessarily prevent additional charges.^2^
Submit the charge details through Microsoft’s investigation route
Not having a payment method visible in your account means there is nothing useful to remove from that account. Instead:
- Open Microsoft’s Manage your payments page: https://go.microsoft.com/fwlink/?linkid=2246882
- Sign in and select Investigate.
- Enter or match the charge details requested by the investigation process.
- Save screenshots or case numbers for your bank dispute.
Microsoft lists other possible sources—including recurring billing, purchases by somebody with access to the card, retried declined charges, and in-app purchases.^2^
If you have ever used another Microsoft account—or knowingly allowed a family member to use this card—check that account’s order history. Do not create or add the compromised card to a new account merely to search for the transaction.
Contact Microsoft Support with the bank’s transaction details
Use Microsoft’s support route:
- Open https://go.microsoft.com/fwlink/?linkid=2258619
- Enter unauthorized billing charge not in my account.
- Select Get Help, then Contact Support.
- Provide the exact merchant descriptor, dates, amounts, currency, and bank transaction references—but never provide the full card number in chat.
If the payments belong to an unknown person’s Microsoft account, ordinary billing support may be unable to disclose or investigate that account directly. Once your bank opens a formal dispute, Microsoft can respond through the card issuer’s dispute process.^3^
If the statement descriptor is misspelled, uses an unexpected domain, or does not start with the expected MICROSOFT* wording, flag that to the bank as possible merchant impersonation rather than assuming Microsoft processed it.
