When attempting to connect to Exchange via Outlook from inside the domain, I'm unable to connect to the server. I have encountered the following errors:
The name of the security certificate is invalid or does not match the name of the site.
There is a problem with the proxy server's security certificate, %s. The security certificate is not from a trusted certifying authority. Outlook is unable to connect to this server. (%s)
