Here's my configuration:
SBS2003 with Exchange
Externally hosted ISP (mail.ourcompany.com) for mail with Exchange set up to pull POP3 into local mailbox
One person in the company needs to receive/send email from the company email address. I set him up on our external ISP as firstname.lastname@example.org. He can receive/send email just fine - as long as it is from somebody outside our company.
When another employee sends him an email (i.e. from Joe@ourcompany.com to Sam@ourcompany.com), the server thinks Sam is an internal exchange client and cannot resolve the address. I do not have Sam set up as a user on the server.
Anyway to force internal email to route to the external ISP? Or do I have to set Sam up as a user on the server and give him OWA access??
