I have a windows live account.  When I try to log in (at the Outlook.com page) I receive 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).

However, I do not believe I am signed in at another Office 365 account and would not know how to close it.  Any help would be great.
