I have search on and on for a solution. The solutions I found do not directly address my concern. We are running SBS2003. Email configuration goes as follows: POP3 mailbox to send/recieve emails. Exchange mailbox: mostly used for shared calendar/contacts. The main issue we are running into is that when a user forwards and existing email, it will return underliverable. If the user creates a new message, copies and pastes the email they want forwared into the new message, it will send just fine. The configuration works great except for this minor issue. I have changed the global policy to update the email addressess to the proper FQDN. I find it odd that all emails send fine but when a user forwards the email to an address, it does not send. Thank you in advance.
