Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
To ensure I fully understand your situation and provide the most effective assistance, I’ll need a few additional details, such as:
Could you please check the inboxes of all accounts you currently use (personal, work, or school accounts) and see whether you have received any emails related to a Microsoft subscription, renewal, invoice, or payment? If so, please share any non-sensitive details from the email (for example, the subscription name or the email domain involved, while excluding personal information).
Have you ever used any other Microsoft accounts in the past, including personal Microsoft accounts, work or school accounts, trial subscriptions, or accounts created with a different email address? Or did this charge appear completely unexpectedly?
After reviewing the billing description on your bank or card statement, could you please provide the exact merchant description shown for the $9.99 charge? This may help identify the type of Microsoft service associated with the transaction.
An update would be appreciated.
