Email account shut down?

Hi There, 

I think my university hasn't put me on their new system because I've graduated. Is there any way i can still access my emails? I can't sign in because i get this error.

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).

Please help,
Nikki
