We are using Microsoft Exchange 2003 SP2 in a Windows Server 2003 R2 SP2 Cluster Environment and mail is working fine. Users are connecting from Outlook via Exchange to the server.
Now, we have a new requirement, the users must be able to access mailboxes using a POP3 client as well. We do not want to stop our current mode of user connection just add the option to use POP3. The server is been running beautifully for one full year and POP3 has never been configured.
Please let me know what steps should I take, please specially highlight the steps related to the fact that it is a Windows Server 2003 R2 SP2 Microsoft Cluster Environment.
