I am installing Exchange 2010 for the first time on a 2008 R2 Server to replace a legacy install of 2003 SBS (which was installed before I joined the company).
The 2008 R2 install has a FQDN formatted as mydomain.local.
Our web hosting is via a third party server (and we have control over subdomains etc)
During the install of Exchange 2010 I am asked for a Client Acces Server Domain name.
Currently to access the Webmail and associated services on our 2003 box you have to type the ip address followed by /exchange
Can I simply use something like mail.mydomain.com for the exchange external domain and create a subdomain in the DNS of my web server to point to it?
I am looking for confirmation that I will not be creating a conflicting entry with AD and that I am not backing myself into a corner :)
