We are trying to implement a dual heading of email access
where the clients recover AND send their email using a
remote POP box. We are using .OST files rather than .PST
because we need Exchange Server to hold a mirror of their
emails. All works fine except if you email another client
of the Exchange server in which case the email is not sent
out to their POP box but retained by Exchange Server
internally. The trouble is that the client may be working
off-site and expects all their email to be in the POP box.
What settings do we need to change to force Exchange
Server to leave outbound emails alone and let them go
outside to the POP box in all cases?
