Question with Outlook is replacing Windows mail

Hi, I am a Windows Mail user and the interface is greater because I can see how much mail I received from my several email accounts directly (first image).

However, the new Outlook  is replacing and it does not have this interface, I have to click one by one to see the update of each email which makes me lose some important emails already. I wonder if Outlook also provides a similar interface but I don't know how I activated it in the setting.
