Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Use Microsoft’s Manage your payments page to investigate the $99.99 transaction; if it cannot be matched to any account or authorized purchase, report the card as compromised and dispute the charge with American Express.
Identify the charge
- Sign in to the Microsoft account you normally use and open Manage your payments.
- Select Investigate beside the unrecognized charge.
- Repeat this for any other Microsoft accounts you use, including accounts belonging to family members who may have access to the card.
- Compare the transaction date, amount, and card details with the AMEX statement.
Microsoft lists several possible explanations: recurring subscription billing, a family member’s purchase, a previously declined payment being retried, a shipped preorder or split order, or an in-app purchase.^1^
If it is an unwanted Microsoft 365 renewal
- Open Microsoft Services & subscriptions using the account associated with the transaction.
- Find Microsoft 365 and select Manage.
- Select Cancel or Upgrade or Cancel and complete the prompts.
- The cancellation process automatically determines whether the purchase qualifies for a refund; cancellation does not always produce one.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
If the page displays Turn on recurring billing, the subscription is already scheduled to expire and should not renew again.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365")
If the subscription was purchased through Apple, Google Play, or another retailer, cancellation and refund requests must be handled by that seller rather than Microsoft.
If no Microsoft account shows the charge
Contact Microsoft Support, enter unrecognized billing charge, select Get Help, and then choose Contact Support if offered.^1^
If Microsoft cannot identify an authorized transaction:
- Contact American Express immediately and open a dispute. A bank dispute for a transaction made without consent is a chargeback.^4^
- Tell AMEX that the card details may be compromised, not merely that one charge is disputed.
- Ask whether the card should be blocked and replaced, because disputing only this transaction does not prevent additional fraudulent charges.^1^
Do not post the full card number, transaction reference, or account credentials here.
