Using Classic Outlook on Windows for personal email, calendar, and contact management
Greetings!
This is Tin, sorry to hear that you're not able to receive emails on your account. May I know how do you access your account, via app or browser? Is your account signed in to other device and were you able to check if you were able to receive email from there? Kindly try to access your email here via browser: https://outlook.com and see if you will be able to access it and see if you have new emails received. Then if its working from there, I will suggest you to sign out and sign back in your account on your app.
Please let me know how it goes.
Thanks,
Tin
