Hi
Can't sign into outlook.com account. Get error: 'This account can't be used to access Outlook.com 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 have tried the way by moderator Jen_C: http://answers.microsoft.com/en-us/windowslive/forum/mail-signin/error-youre-currently-signed-in-with-an-office-365/670d4e97-ff7d-4459-a325-d3c3f76019c6
Trying was unsuccessful.

P.S. I have never registered in office365 & my mail don't ending with .edu
