I'm pretty new to certificates in exchange. When we migrated to exchange 2010, i noticed users get a certificate prompt when the mailbox is moved because its not trusted. I know I can just install the certs, but I want to buy a trusted one.
How many do I have to buy? I want to enable activesync and owa eventually. Can I buy just 1 and assign it to different roles or do I have to buy 1 for each role.
