Will EV SSL certificates work with Exchange? Or must they be UCC?

hi guys

Does Microsoft Exchange both on premise and online accept EV SSL certificates? Or must they be Unified Communications Certificates for your OWA  and other web services to work?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

EV stands for Extended Validation, which implies a different (more thorough) validation process to be performed by the CA before emitting the certificate. Other than that they are the same (apart from any difference introduced by the CA you're uying the certificate with)

would be a lot more costly for no difference.  an EV is used to show a USER that extended validation was performed. Machines don't care and you will need more of them since they only support one SAN

Thank you Michaelangelo.
EV certs do support multiple SAN, depending on the vendor.
