How do I address an archbishop?

I am going to a meeting with the archbishop in a few weeks, and a friend of mine told me that the proper way to refer to an Archbishop is “Your Grace” and a bishop as “Your Excellency.” I always referred to our Archbishop as “Your Excellency.” Can you please tell me which way is proper?
