One of my clients has Exchange 2003 and internally it is referred to as mailserver.myinternaldomainname.local On the internet of course it is called mail.ourdomain.com
Outside the firewall our iphones work just fine using mail.ourdomain.com but when they connect to the corporate wireless they can not resolve mail.ourdomain.com and need to access the server using the internal name.
New versions of Exchange handle this with autodiscover but Exchange 2003 does not do this. I can work around it by having two exchange accounts setup on their iphones but that is not ideal.
Is there an easy way to make this work both internally and externally? Is it as simple as putting an entry into the internal dns for mail.outdomain.com and point it to the exchange server or will that cause other dns issues?
