I have tried multiple different browsers and they all fail

I'm able to login using the outlook android app, however the inbox is empty when I try to check it.

    There seems to be an outage with Outlook this morning as others are reporting the same 500 server error. Only options are to either await a fix or report it to Microsoft:

    I would recommend sending Microsoft feedback via the app - Windows key + F key or via the web:
