Hello all - I have a new build Exchange 2010 server with SP1. It's an DC on it's own for security and is located on the WAN side of our LAN.

What I'm trying to do (and loosing my mind trying!) is to create a public address that's different from my actual domain. I have the domain setup and forwarded to my internal IP but yet I'm having no joy.

Right - I'll try to explain this properly. MyMX records, and ISP security is handled eleswhere. I've had the correct ports and protocols opened to allow Exchange to work. This server is in addition to a Mailenable server currently running. This server will continue to run and serve the users - the EX2010 will serve new users and we will migrate across when possible.

I have had my ISP create the record exchange.myexistingdomain.co.uk ( We're a public body so our domain control is limited). This does trace back and seems to work as expected - but no OWA!  I named the new server exchange.existingdomain.co.uk to match the public address, however my new EX2010 will use the MX records of  exchange.mynewdomain.com. The MX records are for the .com address have been modified and it's working to a degree. Mail sent to user@mynewdomain.com works. I can't send successfully though and I can't access OWA externally.

I will eventually want EX2010 handling all mail from existingdomain.co.uk and mynewdomain.com but for now I need Mailenable to continue to handle existingdomain.co.uk.

My queries (if you're still reading any some of that makes any sense!) is....

Can I have my new EX2010 server having an external address that is different to it's domain name?

Any clues why external access doesn't work? localhost works well and v v fast but just not externally.

Thanks everyone!

Can it have an external address different to its domain name? Yes.

Where to start if external access is not working? Here.
