We are currently using Exchange 2000 on our Small Business 2000 server for internal email. Our outside email is received by Microsoft Outlook connecting to our mail server at a third-party Internet service provider (ISP). How can I configure Exchange Server to retrieve the email for users and then configure Microsoft Outlook to retrieve them from Exchange instead of the Internet?
Small Business Server (2003, 2000 and 4.5) includes a component called the POP3 Connector that can be configured to connect to your ISP and retrieve mail for the users in your organization, and then move it to the appropriate mailboxes. It is tied into the Small Business Server Internet Connection Wizard. Check out the Help on your system, or you can access it directly inside Exchange System Manager under Connectors. Microsoft has a TechNet guide that examines important considerations when
connecting a Small Business Server network to the Internet
, including the types of available connections and the Small Business Server Internet Connection Wizard.
After you have the connector set up, you can remove the account from your Outlook profile. Depending on the version of Microsoft Outlook, you also might want to change the Outlook Mode from Internet/POP3 to Workgroup/Exchange.
There are also a number of add-on products for POP3 connector functionality (search for POP3 Gateway Exchange). If simple and inexpensive is what you want, I particularly like Mail Redirect from Helexis Software. As the Microsoft POP3 Connector only works with SBS, this is a great solution for someone running full Exchange and needing a POP3 gateway.
