How to block or report suspicious access to Authenticator

Recently my MS Authenticator pop up several times, someone try to access my Microsoft service. I pressed "block" but it still happening.

 

I feel so bad that beside pressing "block" I can do nothing on it. Unlike google I have no way to further investigate it or report this issue to Microsoft.

 

What should I do?

  • If you deny Authenticator approval notifications, that should be sufficient for the system to eventually recognize these if they happen on a large enough scale from similar IP addresses. You can also review any sign-ins using https://mysignins.microsoft.com.

      Sorry I should mention that the account being unauthorized access is my personal account (by Office 365 home edition subscription).

      When I try to login https://mysignins.microsoft.com the page prompt:
      You can't sign in here with a personal account. Use your work or school account instead.
