Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, thank you for reaching out to Microsoft Q&A.
If you notice an unknown charge on your Microsoft account, first visit your Order History page to see which product or service you are being charged for.
To do this, sign in with your Microsoft account here:

If you understand why you were charged, you can go to the Subscriptions page to review, manage, or cancel your subscription to avoid future charges.
If you still can’t determine the reason for the charge, run the troubleshooter in the article below to help investigate why you were billed.
