If the compromiser is still signed into your account, they will most likely use your info, especially when your bank or social media accounts are linked to your email. But try using the "Sign me out" option in the Advanced Security options and it will help you log out within 24 hours from every browser and app that your account is currently logged into. You can go to https://account.microsoft.com/security?refd=acc... then scroll down to the Sign me out section.
I hope this would at least help ease your mind.
