“We’re updating your inbox” is always showing when I sign in

I've tried every single possible way to get into my inbox but it simply isn't helping. This happened ever since i changed my hotmail.com to outlook.com. I've tried emptying the cache, browse history, deleted my aliases, updated my browsers, checked on my mobile and different browsers, looked into every single possible thread but there is no solution for me. Can anyone help me? Please! I need to get into my emails ASAP.
