After a few days of working through the install of Exchange 2003, I have successfully installed Exchange on our company's single domain. On our network we have one DC server and a seperate server for Exchange (relative to question). Currently, we outsource our email to a web hosting company where all of our employees use Outlook 2000/2002/2003 and download their email via POP3. I have been researching and reading on the steps, now, to move all of our employees emails, contacts, calendar, tasks, etc. (.pst) over to Exchange 2003 and 'turn it on." I am utterly confused on how to move forward with this. I am looking for any information on steps to migrating POP3 accounts to Exchange 2003 and how to turn on Exchange 2003 in our domain.
