Exchange hosting

I have a client using exchange hosting at another provider for email.

Would this be the same exhange hosting option on cluster2, he has up to 100 users, what is the best plan to offer him.

Thanks

you realize 100 users will cost over $995 a month?

Thats what I was afraid of. IS there another cheaper alternitive.

with exchange not really, at that cost we are not even making anything to be honest.
