I need to forward an email for a user from one domain to another, in 2003 I would do this by creating an accound in the ADUC and then forward the emails to that user.in 2007 however when I create a user in ADUC and then go into the system manager and delivery options I only get the option to forward emails to the exchange domain users. The user that I created in the ADUC does not come up as an option. How do I forward these emails?

Don't use ADUC, use the Exchange 07 tools to setup a FW to a contact, or an exchange 07 hub transport rule.

how do you use exhange 07 tools to fw to a contact, I only seem to have the abiltiy to forward to other emails on the same exchange box.
