hotmail vs outlook.com vs 365 outlook, how can you tell which is being accessed in my Microsoft account?

My Microsoft account was originally using Hotmail.  My husband abandoned Windows for Linux now I have to manage my email account *** Email address is removed for privacy ***.  When I log in Outlook seems to be the program but I don,t see all the items on the menu bar that I see when I Google how to manage rules and perform Sweep to attempt to minimize my junk mail folder which I am getting hundreds of unwanted emails.  Did you notice I am nontechnical?
