microsoft mail

Somehow I have blocked mail from coming into my mail mail box. as you can see  I know nothing about computers. I am going to take some classes this summer anyway. when I go to mail there is nothing there but when I go to my account I can find it there. The simple way has been to refresh my computer but then I have to redo a lot of things. can someone help me. I have already signed up for classes. One more thing please be a little kinder to those who are just beginning especially people who have a few years on you. We are not dumb just grew up in a different world then you.
