I was double charged

Cancel only the newly purchased storage add-on—not the existing Microsoft 365 Home subscription—and the cancellation process will determine whether the immediate charge qualifies for a refund.

Request the refund without changing the existing plan

1. Sign in to the Microsoft account used when accepting the extra-storage offer.
2. Open Services & subscriptions.
3. Locate the additional OneDrive/storage subscription by matching its purchase date and price to the unexpected charge.
4. Select Manage, then Cancel for that add-on only.
5. Review the cancellation screen carefully:
   • If it offers Cancel immediately and get a refund, select that option.
   • Do not cancel the existing Microsoft 365 Family/Personal subscription you want to retain.

Microsoft determines refund eligibility automatically during cancellation. In most cases, an initial purchase may be refundable within 30 days or before its first recurring billing date, whichever is sooner. The most recent recurring charge may also qualify when canceled within 30 days, subject to the stated limitations.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")

Additional storage is a separate purchase that extends the storage included with Microsoft 365, so removing that add-on should not require canceling the underlying Microsoft 365 plan.^2^

If the add-on or refund option is not shown

Check the Microsoft account’s order history for purchases made at the time of the notification. If there are two bank charges but only one matching order, open Payment options and select Investigate; this can identify a purchase associated with another Microsoft account using the same card.^3^

If the transaction appears but cancellation does not offer a refund:

1. Open Contact Microsoft Support from the support link on the billing investigation page.
2. Enter unexpected Microsoft 365 storage charge and select Get Help.
3. Select Contact Support if self-service does not resolve it.
4. Tell the billing agent:
   • The offer stated that payment would occur at renewal.
   • The charge was taken immediately.
   • You want the new storage add-on refunded and canceled.
   • You want the existing Microsoft 365 subscription left active.
5. Save screenshots of the charge, order details, and any wording from the notification.

Microsoft Support can review the account and transaction; a public Q&A forum cannot access payment details or issue the refund.^4^

If the purchase was processed through Apple or Google Play rather than Microsoft, the refund must instead be requested from that store.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
