Does anyone know how I can configure exchange 2003 to display an alias e-mail address on sent messages? I need to have their old e-mail address show up on sent messages rather than the exchange servers address because their customers are use to seeing the old addresses. All mail from their old addresses is forwarded to the exchange server via the pop3 connector and outgoing mail uses an smtp relay through their ISP and different mailboxes will need different outgoing addresses on the mail. Thanks

You can change the recipient policy Add the old address to the policy And make the old address default in the policy RUS needs to complete synchronization... Then users will send messages with old address Deli
