Microsoft Exchange Fordward to another domain

Two domains. ABC & XYZ. One phone system. Phone system forwards all user voicemails to his/her email box. The phone system is provided with a valid email address, port, and server name of domain ABC in order to forward the voicemails to the appropriate users mailboxes.

The phone system is able to forward the voicemails to any users on ABC, but NOT XYZ. I assume this is because the exchange server on ABC is not configured propertly. How can I fix it?

The email server on ABC domain is exchange 2007. THe email server on XYZ domain is exchange 2003. Both domains are completely seperate in AD, but have LAN connectivity.

You can link together 2 separate Exchange organisations (either separate forests or domains) by making one non-authoratative for the SMTP email domain.  Is this what you're meaning ?

yes I think so. any links on how to do that? I wantmail server on domain ABC to be able to "forward" an email addressed to a user on domain XYZ to email server XYZ.

Before I go any further could you just clarify:

Are these users in both of your domains "sharing" the same SMTP email domain addresses ?

Not sure if you're still looking for info on this, but here are some links on sharing SMTP address space in Exchange 2003, forwarding messages to a foreign messaging system that shares the same address space and authoritative and non-authoritative domains in Exchange server 2003.

config:


192.168.1.1 - voicemail/phone system for ABC.com and XYZ.com

192.168.1.11 - ABC.com exchange 2008 server
192.168.1.12 - ABC.com domain controller - Server 2008 R2

192.168.1.21 - XYZ.com exchange 2003 server
192.168.1.22 - XYZ.com domain controller - Server 2003

192.168.1.1 - logically configured to SEND "voicemails" as emails with .wav file attachements to server: 191.168.1.11. All users on domain ABC.com, receive those emails without issue. All users on domain XYZ.com do not. The configuration settings for 192.168.1.1 cannot be changed. Thus, I want server 192.168.1.11 to forward the "voicemail" emails to 192.168.1.21.

Note -- I am domain admin of both domains. Essentially -- we are two seperate companies, sharing a phone system.

I neded up allowing the exchange 2003 server to act as a SMTP relay for the ip address of the exchange 2008 server.

Example:

8 Simple Steps:

Log into Exchange 2003 server and start Exchange System Manager.
Expand the organization_name object, and then expand the Servers node. Expand the server_name object of the server on which you want to control mail relay, and then expand the Protocols node.
Expand the SMTP node, right-click the virtual SMTP server on which you want to control mail relay, and then click Properties
Click Relay.
In the Relay Restriction dialog box, several options are available. The Only the list below option is enabled by default; the list below this option is empty.
Click Add. Enter the IP address of the server running eSupport (Ex: 192.168.1.2).
In the Relay Restrictions dialog box, click OK.
Click Apply, and then click OK in the Default SMTP Virtual Server Properties dialog box.
