You’re currently signed in with an Office 365 email account, which can’t be used with Outlook.com.

My system was crashed yesterday and I had to reinstall windows xp, the problem is I can't access my university email. every time i use internet explorer or even google chrome to access the email I get this message " You're currently signed in with an Office 365 email account, which can't be used with Outlook.com. Please click here to sign out of your Office 365 account, then use another Microsoft account to sign in to Outlook.com (for example, your hotmail.com, live.com, or msn.com account). "

I followed the instructions and cleared the cache and I even used my friend pc to access the email but It still in vain. I can't access my email, please help
