Exchange not responsible for entire domain

I have a client that bought a franchise. Everyone in the office what an E-mail address user@franchise.com.  The users at the Corporate office also have an e-mail address user@franchise.com. When a local user tries to e-mail someone at corporate the mail is returned beouse Exchange is not aware of the corporate users. Is there a way to tell Exchange, if it is not aware of a user forward it to the SMTP connector for internet mail?

Thanks for your help on this,

DWordenJr.

In the SMTP Properties you can set the Server to which all the undelivered mails are forwarded.

If you use the above tip and the corporate site hosts multiple e-mail domains, then the franchise site will also receive ALL unresolvable mail to ALL e-mail domains, not just the franchise.com domain. I think this is not desirable.

To enable unresolved forwarding for the franchise.com domain only, disable the check box "This exchange organization is responsible for all mail delivery to this address" in the Exchange Recipient policy for the franchise.com domain. This determines whether this exchange organization is the 'end point' for this mail domain. If a recipient for this domain is unresolved, then the mail is treated as a message to a foreign domain, otherwise the mail is delivered locally.

Depending on the configuration of the SMTP Connector (using DNS or smart host) you will have to create an MX record in DNS for the franchise.com domain, or create a special SMTP Connector for the franchise.com which delivers mail to [ip-address].

Sorry I didn't back to this sooner, I was out of town for a couple days. I don't see were there is a checkbox for "This exchange organization is responsible for all mail delivery to this address". Maybe I am missing something or going to the wrong place. I think with a little more help I will have this issue resolved.

Thanks.

In the Exchange System Manager, browse to Recipient Policies, then open the recipient policy that has the @franchise.com domain listed on the 2nd tab. Select the @franchise.com domain and click Edit. The checkbox is there.

The only restriction is, the toggle can not be disabled for the Primary address (in bold) of the Default Recipient Policy.

For a detailed explanation of the toggle you are about to de-select, see
