Unauthorized withdrawal from bank account by Microsoft.

Contact your bank immediately to block further Microsoft withdrawals, then use Microsoft’s payment investigation and Billing Support channels to identify the unknown subscription and request cancellation and a refund.

1. Protect the checking account

Tell the bank that:

• You do not recognize the Microsoft withdrawal.
• You need recurring payments to that merchant blocked.
• If it was a debit-card transaction, the card may be compromised; ask whether replacement is necessary.
• If it was a direct bank-account debit, provide the bank’s transaction reference and ask about its dispute procedure.

Merely disputing one transaction may not prevent another charge, so explicitly request protection against future withdrawals. Microsoft also recommends contacting the payment provider when payment information may have been compromised.^1^

2. Investigate the charge without knowing the subscription number

You do not need a Microsoft subscription number to begin:

1. Open Manage your payments.
2. Sign in with any personal Microsoft account you may have used.
3. Select Investigate beside the unrecognized charge.
4. Repeat this with any other email address that might have been used for Microsoft, including an Outlook, Hotmail, or Live address.

Possible explanations include recurring billing, a purchase by someone who had access to the payment method, a previously declined payment being retried, or an in-app purchase. Those are possibilities—not confirmation of what happened here.^1^

3. Contact Microsoft Billing Support because the purchasing account is unknown

If the charge cannot be found under an account you can access:

1. Open Contact Microsoft Support.
2. Sign in with your own Microsoft account; create one if necessary.
3. Enter Unrecognized Microsoft 365 charge and select Get Help.
4. If the automated results do not resolve it, select Contact Support and choose the billing/subscription option offered.
5. Provide:
   • Withdrawal date and exact amount.
   • Bank’s transaction description and reference number.
   • Last four digits only if a debit/payment card was used.
   • A redacted statement showing the transaction.
   • Any email addresses that might have been associated with Microsoft.
   • The fact that you suspect duplicate subscriptions but cannot access or identify the purchasing account.

Do not post a full bank account number, full card number, statement, or other financial details in this public forum.

4. If Support identifies the subscription

For a Microsoft 365 subscription purchased directly from Microsoft:

1. Go to Services & subscriptions using the purchasing account.
2. Select Manage beside the subscription.
3. Select Cancel or Upgrade or Cancel.
4. Complete the cancellation process; Microsoft displays refund eligibility during that process.

Cancellation is required to check refund eligibility, but not every cancellation produces a refund.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "How to get a refund on a Microsoft subscription | Microsoft Support")

If Turn on recurring billing appears instead of Manage or Cancel, that subscription is already scheduled to expire and should not renew.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Unable to cancel your Microsoft subscription | Microsoft Support")

Conditional cases

• Germany: If the subscription was purchased in Germany, Microsoft provides a cancellation process that does not require signing in; transaction details are required. Use Cancel a Microsoft subscription acquired in Germany.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "How to get a refund on a Microsoft subscription | Microsoft Support")
• Apple, Google Play, or another retailer: That seller—not Microsoft—must manage the cancellation or refund.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Unable to cancel your Microsoft subscription | Microsoft Support")
• Microsoft cannot locate the transaction: Continue the unauthorized-transaction dispute with the bank and retain the case number from Microsoft Support.
