I'm trying to forward to an external email address using Exchange 2007.
e.g. if someone sends an email to email@example.com I want to forward it to firstname.lastname@example.org.
I've created a MailContact with an external email address, as outlined here.
However, this only seems to work if I send an email from within my organisation. If I log onto gmail for example and send an email to email@example.com it doesn't seem to get forwarded.
Is there something else I should be doing?
