S/MIME and certificate
New to Exchange2010 .Have a question regarding the encryption.
We have EXchange2010 and the CAS server and it has ssl SAN installed.
If we want to enable S/MIME at end users outlook.
Do we have to install third-rate trusted certificate?
or
We will be ok with internal CA and install the certificate to users via AD?

Carol,
Thank you for your reply.
I am having problem of understanding this ssl and S/Mime.
Hope you will put me in the correct direction.
i noticed that one SAN certificate has been installed on all four CAS servers(may be export or copy)
When you say third party from a trusted source, Say for an example we have 100 outlook clients.
we able to install one certificate at all 100 users computers like the CAS servers?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
However in general you now should always go with a third party certificate from a reliable provider.
Self signed certificates really are not a good idea unless you have a fully published PKI, and if you had that you would not be asking the question.
