Add outsider to GAL & enable internal users to send him mail

[Guest]

Dear All
How do I add outsider to GAL & enable internal users to send him mail .
I understand I have to add him as a user in AD, but how do I define his
email address, so the mail will get sent to him outside our organization.
Thanks,
Gila

DEAR All,
The answer to my question is in 281926 microsoft knowledge base . "How to
configure a mailbox to forward mail to a mail-enabled contact."
