We do this by pointing all users to the external address regardless of where 
they are located.

Subject: Exchange 2007 and SSL certs for internal and external use

Hi chaps,

I have an Exchange 2007 server here on which we have setup an SSL certificate 
(in the name of mail.mydomain.com). This works great for users outside using 
Outlook 2007s Outlook Anywhere feature. However, internal users get a warning 
stating that the SSL cert name doesn't match the server. It's not the biggest 
issue, but it's...untidy.

What's the best way to handle this? Obviously I can only attach one SSL cert to 
the Default site in IIS on the Exchange box and the internal domain 
(mydomain.local) is sufficiently different from the external one (mydomain.com) 
that we can't get an SSL cert to cover both.

Is there a way to create a new IIS site that still points at the same exchange 
folder structure as the current Default Site but that is set to accept a 
different hostname? That way I could have one site for the internal users 
hitting blue-server.mydomain.local and one for the external users hitting 
mail.mydomain.com and attach a correct cert to both.

Can this be done ?

Olly
