I have tried from different computers and different browsers, no change. Also verified there's nothing wrong with the settings as it's possible to log in to other accounts from this computer. 
Anyone got suggestions as to what might be wrong?

Sorry, there seems to be a problem with Hotmail right now
What you can do:
Hi there, I have been trying to login to my hotmail account since yesterday.  I have tried clearing the cache, and have tried 2 different computers with no success (including Firefox, Safari, and Internet Explorer).  This message keeps on coming up.  How can I fix this?  I really need to my e-mail up and running today for work.  Thanks.
I JUST GOT AN EMAIL FROM SOMEONE CLAIMING MY ACCOUNT HAD BEEN ACCESSED FROM SEVERAL DIFFERENT COMPUTERS AND MULTIPLE WRONG PASSWORDS WERE ENTERED....THEY ARE WANTING ME TO UPDATE MY PROFILE INFO AND SAY IF I DONT DO IT IN 3 DAYS I WILL LOSE MY ACCOUNT PERMANATLY. HAS ANYONE ELSE GOTTEN THIS EMAIL? IF SO IS IT LEGIT?
I use 3 different computers and on one of them - the one I use most - when I click to reply to an email the address of the pesron I am replying to does not appear. It must be something to do with the settings on that computer but I cannot find out what!
Since this morning, after I log in to hotmail, I cannot see any email in my account--it returns a message saying there is a problem with hotmail right now, so try to return to hotmail.  Please could someone suggest what to do??

I've tried logging on to different computers, but it has not helped!
All suggestions appreciated!
