Our company is temporarily using 2 domain names for our Email(companyname.com and companyname.ns.ca).
The .com domain is managed locally on our newly deployed Exchange 2003 server and ns.ca is still managed externally by our ISP. I have some departments using exchange server and other department are not set up on it yet. They use outlook to POP their email from our ISP.
The problem is when users on the exchange server send email to their colleagues who are still using ns.ca domain, the Exchange server is rejecting the email. It seems that is assuming the ns.ca users are local since their domain name starts by the same name.(I included the error message below)
How can I make Exchange know that these users are external and make route the email the recipients.??
(“The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
I’d appreciate any help.
Thanks.
