Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
To locate and cancel a Microsoft 365 subscription when the account email is unknown, use both self-service steps and direct Microsoft Support, focusing on billing information and the card being charged.
- Check all possible Microsoft accounts for the subscription
- Go to the Services & subscriptions page: https://account.microsoft.com/services.
- Sign in with each Microsoft account that might have been used (different email addresses).
- Under Services & subscriptions, look for an active Microsoft 365 subscription.
- If found, select Manage next to the subscription. If Turn on recurring billing appears instead of Manage, the subscription is already set to expire and will not be charged again.
- Cancel the subscription and trigger refund eligibility check
Once the correct account is found:- On the Manage page, select Cancel (or Upgrade or Cancel, depending on what is shown).
- Follow the on-screen steps to complete cancellation.
- If the subscription is a Microsoft 365 Basic, Personal, Family, or Premium plan purchased from Microsoft, cancellation is required first to check refund eligibility. See the guidance under Microsoft 365 in the refund article: How to get a refund on a Microsoft subscription.
- If the subscription was purchased via Google Play or Apple App Store
If investigation shows the charge came from an app store instead of Microsoft directly:- For Google Play purchases, follow Learn about Google Play refund policies.
- For Apple App Store purchases, request a refund from Apple support.
- Use Microsoft’s billing support when the account cannot be identified
If none of the likely Microsoft accounts show the subscription, or if there are duplicate/unknown charges:- Use the billing investigation guidance: How to investigate a billing charge from Microsoft (linked from the Q&A context).
- Then contact Microsoft Billing Support so an agent can look up the subscription using billing details (card, transaction info). From the Q&A guidance, go to the general support entry point: https://support.microsoft.com/contactus, select Microsoft 365, choose a billing-related category (for example, Billing and Payment updates), and use Chat with a support agent in your web browser.
- If a duplicate or fraudulent charge is suspected
If Microsoft Support cannot locate the transaction under any account, or confirms it is not associated with a valid subscription:- Contact the bank or card issuer to dispute the charge as unauthorized or fraudulent.
- The bank may block the card and issue a new one to prevent further charges.
- If a refund is needed after cancellation
After cancellation, check refund eligibility using the Microsoft subscription refund guidance: How to get a refund on a Microsoft subscription.
Note that not all cancellations result in a refund, and in some countries (such as Canada, Israel, Korea, Turkey, and certain EU countries for longer-term renewed subscriptions) prorated refunds may apply.
