Cannot sign into my hotmail?

New Email
I tried to sign into my hotmail account on my MacBook and it said "service unavailable". So I then tried it on my iPad and my iPhone and all that came up on all 3 was "service unavailable", so I tried logging in to an old hotmail account that I no longer use and it worked fine! What is wrong with my account?! I need to access my emails!!
