how do i add a Hotmail account to my phone

[Mayra429]

I have 2 yahoo emails, 1 gmail and 1 Hotmail and it's not letting me add it. I called my carrier T-mobile and they told me that the phone doesn't support it, is this true? I had to download a separate app outlook to add my hotmail account. But im not Satisfied, I would like to have them all together in the app that the phone offers...please help
