I am administering a site having the following services: OWA, OMA, and push mail using MS Exchange Server 2003 SP2 and Windows Server 2003 SP1.
Everything is ok but we are using a self-signed certificate.
I want to buy a certificate to use it instead of the self signed one.
Would you give me recommendations and guidance:
from where to buy? what type of certificates to use?
I browsed Verisign and Thawte and got confused.
