I have set up one of our internal email boxes to forward to an external email address and then have also checked the deliver message to both forwarding address and mailbox. This forwarding is working fine IF the email comes from an internal email. When sent from an external email, the forwarding does not work. The email does still display in the email box but I need the forwarding to work.
Is there something I'm missing in the Delivery Options or else where to make this work?
