Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Use this Microsoft billing investigation path first:
- Go to the Manage your payments page of the Microsoft account dashboard and select Investigate.
- Review the charge to identify the most likely cause. Microsoft lists these common causes for an unrecognized charge:
- a subscription with recurring billing enabled
- a purchase by someone known to the cardholder, such as a family member
- a previously declined charge that was charged again
- a pre-order or split order that shipped
- an in-app purchase
- Check order history for multiple purchases of the same amount close together.
- If the charge does not appear in the Microsoft account order history, another Microsoft account may be using the same card. From Payment options, select Investigate to search for other accounts using the card.
For the “many months” of $9.99 charges, also check whether this was a recurring subscription charge rather than a one-time purchase. If a subscription was cancelled very close to the billing date, a payment can still be taken; cancellations must be made more than 2 days before the billing date.
If the charge is still not recognized after using Investigate, contact Microsoft Support through Get Help and Contact Support.
If there is any sign the card details were used without authorization, contact the bank or payment provider immediately and report the card as stolen or compromised to prevent further charges.
