Can I sign in with my Caleb Microsoft account?
Yes — the sign-in page has a Microsoft button for your @calebuniversity.edu.ng account.
On the sign-in page, choose Sign in with Microsoft and use your Caleb email address and its password. It opens the same portal as signing in with your matric number and surname.
If Microsoft refuses your password, reset your Caleb email password first (see the Caleb email answers), then try again.
