- Scenario
- Reviewing bank or credit card statements and discovering an unrecognized transaction from Microsoft.

- An unexpected charge appears on the payment method without a clear indication of which software or service was purchased.

Review Microsoft Account Purchases and Subscriptions
Check your Microsoft account's order history and active subscriptions to match the charge details.
Most unexpected Microsoft charges are tied to recurring subscriptions like Microsoft 365, Xbox services, or purchases made by family members sharing the same device.
Navigate to the official Microsoft account page and sign in using the email address associated with the suspected charge.
Go to the 'Payment & billing' section and select 'Order history'. Look for the exact transaction amount and date to identify the purchase.
Click on 'Services & subscriptions' from the main menu. Check if an auto-renewal or previously free trial transitioned into a paid subscription.

Contact Microsoft Billing Support
Reach out directly to Microsoft Support for a detailed investigation of the unrecognized reference code.

Frequently Asked Questions
Why am I seeing a Microsoft charge I didn't authorize?
Unrecognized charges often occur when a subscription auto-renews, a free trial ends and becomes a paid subscription, or a family member makes an in-app purchase on a shared device.
Where can I find the reference code for a Microsoft charge?
The reference code is typically located on your bank or credit card statement right next to the transaction amount, often alongside merchant details like 'Microsoft Sydney' or similar regional indicators.
Can I dispute the unrecognized Microsoft charge with my bank immediately?
It is highly recommended to check your Microsoft account and contact Microsoft Billing Support first. Disputing the charge directly with your bank before communicating with Microsoft may result in your account being suspended.
How do I cancel a Microsoft subscription to stop future charges?
Log in to your Microsoft account, navigate to 'Services & subscriptions', locate the active plan, click 'Manage', and choose 'Cancel subscription' to prevent further billing.
