I just upgraded Exchange 2003 to 2010. I wanted to get a real certificate for this client. The problem is their internal domain is a vaild Internet domain name ending in .com that is owned by someone else
I can't use that domain name in a certificate.
I know I can get a certificate with just the external domain but I want to elimintate the certificate error that pops up in Outlook on the internal network
How can I get around this problem?.
