I need a refund

Check who processed the accidental charge, then request the refund from that merchant; if the charge was made directly by Microsoft, cancel it through Services & subscriptions to trigger the automatic refund-eligibility check.

If Microsoft processed the charge

1. Go to https://account.microsoft.com/services/microsoft365.
2. Sign in with the same Microsoft account used for the accidental purchase.
3. Find the newly purchased Microsoft 365 subscription and select Manage.
4. Select Cancel or Upgrade or Cancel.
5. Follow the cancellation prompts. Microsoft will display whether the purchase qualifies for a refund and provide the next steps.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")

In most cases, a directly purchased subscription may be refundable when cancelled within 30 days of the initial purchase or before the first recurring billing date, whichever comes first. Refunds are not guaranteed; eligibility is determined during cancellation.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")

If the page shows Turn on recurring billing instead of Manage or Cancel, the subscription is already set to expire and will not renew automatically.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Cancel a Microsoft 365 subscription | Microsoft Support")

If another merchant processed the charge

Check the purchase receipt, Microsoft order history, or card statement:

• Apple App Store or Google Play: request the refund from that store.
• Another third-party seller: contact that seller directly.
• Best Buy: its return policy applies only to the product purchased there; Microsoft’s refund policy does not cover prepaid retail subscription codes.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")

Redeem the unused Best Buy license

For a Microsoft 365 card or digital code purchased from Best Buy:

1. Locate the unused 25-character product key on the card, packaging, receipt, or purchase email.
2. Go to https://microsoft365.com/setup.
3. Sign in with the Microsoft account that should own the subscription.
4. Enter the key and follow the prompts.
5. Confirm that the new expiration date appears after redemption.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "How to renew your Microsoft 365 subscription | Microsoft Support")

A retail Microsoft 365 key can renew an existing subscription by extending its duration.^4^

If no refund option appears

Use Contact Microsoft Support, enter Microsoft 365 accidental purchase refund, select Get Help, and then select Contact Support. Billing support can review the transaction, but the final eligibility decision depends on the purchase channel, timing, subscription type, and region.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
