Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Office Home & Business 2021 is a one-time purchase, not a monthly subscription. A $10.59 monthly charge usually means a separate Microsoft 365 subscription is also active on the account.
Check Services & subscriptions in the Microsoft account used for Office and see whether both of these appear:
- Office Home & Business 2021
- A Microsoft 365 subscription
If a Microsoft 365 subscription is listed, that is the source of the monthly charge and it can be canceled there.
Also, on Mac, Office apps downloaded from the Mac App Store require a Microsoft 365 subscription to create and edit documents. One-time Office licenses such as Office 2021 are not compatible with Mac App Store versions of the apps. Those licenses only work with Office apps downloaded directly from Microsoft.
If the apps came from the Mac App Store, that can explain why a subscription charge appeared even though Office Home & Business 2021 was purchased.
