How do I use my outlook.com account as my primary MS account?

When I originally signed up for my MS account, I used my gmail account.  I have since tried to purge gmail from my life and grabbed an outlook.com address.  What steps do I need to go through to use my outlook.com address to sign into my MS services rather than my gmail account?  I would like to get my outlook.com email from my main MS account, but it's currently that gmail account.  So when I'm signed in to my MS account, I can't get to my outlook.com email...which isn't an optimal situation at all.  Thanks.
