    They will alway get that, unless you install the ROOT certificate of the server which generated the certificte in their "trusted root certificate" store.

    You are better off however just buying an SSL from godaddy, they start at about 60$ for a year

    For external access, you have to purchase the third party certificate for your OWA url (eg. and have the DNS records updated.

    For Exchange 2010 (and 2007) you would be best advised to purchase a SAN / UCC SSL certificate with the following names included: (or whatever you prefer)

    If you install a certificate with the above names then you will stop getting certificate prompts / errors and all aspects of Exchange will work, with the exception of Autodiscover, where you will have to add an A record in External DNS that points to the IP Address of your Exchange 2010 server.

    As mentioned, GoDaddy are about the cheapest place to buy an SSL cert from, but a GoDaddy Reseller account is slightly cheaper.
