The company I am dealing with has 2 different domains externally. Using Exchange as a mailbox collecting the data, I am trying to setup the exchange server to allow simply collecting the email as it is received in from the Outlook Client via POP3. I first setup the exchange mailbox via adding the user to the server. I then added the POP3 accounts. I set the POP3 to be the default and it has the POP/SMTP server settings setup in the account. How can I make sure that the Outlook Client is sending the data from its POP3 account and NOT trying to do so through the exchange? I really just want Exchange to be there as a backup to the clients.
