Check in ESM under ADMINISTRATIVE GROUPS, Your domain/server/identification name, SERVERS, Your server, Protocols, POP3. If the defualt POP3 server is present, you shouldn’t have to configure anything new on the server side. Install Outlook on the client side and configure for POP3/Internet mail versus corporate workgroup mode. If the client is already configured for Corporate mode, you can change that setup to suit your needs. THere are a lot of other variables that could come in to play as to how your clients connect and manage mail, but as to the initial question, the POP3 service should install by default. If it’s not, you can go through the Exchange setup again and install the protocol. HTH!
