Do you have payment card information stored in your Microsoft account? Now the intruder has it. Do you have email addresses stored in your Microsoft account (e.g., you use Outlook email)? Do you have passwords stored there (in Microsoft Edge)? The intruder has those too. Think of all the things you have in your Microsoft account - while you are filling out forms, the intruder has all that information and can make use of it. Take steps to protect your identity.
