My issue is the following, thanks in advanced :). I have a server 2008r2 running exchange 2010. Clients connect externally using outlook 2010 exchange over RPC. I installed a security certificate I purchased from rapidssl.com pointing to the external site name mail.company.com. External outlook connections don’t display the error, however when running inside the network, the error” the name of the security certificate is invalid or does not match the name of the site” shows up.
I’m not using auto discover, I manually configure each client.
