Exchange Certificate Issue (Internal Users)

Hi all,

Bit stuck with this, I have our company wild card cert installed in our new Exchange 2010 server… external users are loving it! But internal users get a certificate error every time they start Outlook. of course it’s going to tell them the name is wrong, because they are using mail server, not to connect.

How do I fix this without getting a new cert? is there some work around?

should not a wildcard cert of


cover it... or not?
are both external and internal domains are same??

Ahh no

External is

internal is

Yeah the error is the name on the security certificate does not match the name of the site.

So only a SAN cert will fix this?
