Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
Sign in with your Microsoft account on the Services & Subscriptions page to check which Microsoft 365 subscription you have:
https://account.microsoft.com/services
If you have the Microsoft 365 Basic plan, it only includes 100 GB of cloud storage and ad-free Outlook email. However, it does not include desktop applications such as Word or Excel.
To use the desktop applications, you will need a Microsoft 365 Personal or Family subscription, , or a one-time-purchase license such as Office Home or Office Home & Business.
Please note that Microsoft 365 Personal and Family subscriptions generally cost more than the amount you mentioned. Therefore, the charge may be for a different subscription or service.
First, check the Services & Subscriptions page to identify the subscription associated with your account. If no matching subscription appears, review your Microsoft account order history or use Microsoft's billing charge investigation tool to identify the charge.
