I am running a SBS 2008 Server with Exchange 2007.The mail is popped to the exchange server. I have several email users in the organisation using the same domain for their email, in a remote location. How do I get exchange to send mail to remote users on the same domain?

Can't you just let them use OWA?

I would suggest configuring Outlook Anywhere in Exchange 2007. Outlook client would be able to connect via RPC/HTTP for Outlook 2003 and for Outlook 2007 they would be using Autodiscovery.

To help answer the question directly, you need to setup SMTP NameSpace Sharing and the following article should help you to understand what to do in order to configure this:


It is not straight forward to configure.

You might also consider not popping the mail for the external accounts into your server and instead, popping the accounts into the other server, or allowing the remote users to POP mail from your server.

The best answer is probably to configure RPC over HTTPS for the remote users as has been suggested above.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Another resource for configuring your server can be found here:


It covers the Internal Relay Domain and this is what you would need to configure for sharing the address space between two servers.

Try using OWA (Outlook Web Access)
Open your browser and type: http://<mailservername>/exchange
if running on secured channel use: https://<mailservername>/exchange

Guys I still haven't found a solution! Let me explain again.
My clients mail is hosted by an external 3rd party Server offsite.The mail is popped to their exchange 2007 server for central management. They have two other remote offices with users on the same domain. Without using Outlook anywhere, how can I route outgoing internal mail to users on the same domain at those remote locations?
