I have a customer with an SBS2003 Server who has a parent company. They currently POP their mail down from the parent company though POP3 configs in Outlook. They would like to take advantage of some of the Calendar funtions, etc that you get with SBS. I configured the POP3 connector to pull mail down from their parent server to Exchange and distribute the email from there. The problem is that they cannot email people that are located at the parent company because the local exchange server says that they're mailbox does not exist. Is there a way to tell the Exchange Server to forward mail to the internet that is not resolved on the local Exchange Server?
