Who is Participating?
Also, don't forget you will need to generate the CSR for the certificate from the Exchange Management Shell. Many of the SSL providers will provide a wizard on their page to assist in the process.

For example:

On IPHONE users are getting...

"Unable to Verify Certificate The Certificate from "" for account could not be verified."
At first glance, it looks like you are using a self-signed or internal certificate. Have you already purchased a certificate from a public Certification Authority?

Alan HardistyCo-OwnerCommented:
Your certificate needs to include the following names to get everything working properly and the best option is to purchase a Multi-Name certificate (SAN / UCC) from a 3rd Party SSL provider such as GoDaddy.
You cannot use the certificate installed by default with Exchange 2010 - it simply will not work and your current certificate is not issued to a Fully Qualified Domain Name - which it needs to be.
