I want to migrate from computalynx cmail to microsoft exchange server 2003 on SBS.
The network is small, 5 users.
The new server is SBS 2003 Premium. The old server is NT 4.
cmail runs still on the old NT server and collects/delivers mail through an ISP.
If the NT server goes offline for any reason, mail is queued at the ISP and is picked up when the server goes online.
Outlook is configured to collect/deliver mail through the NT server, and mail is stored locally on each workstation.
I want to configure exchange server 2003 to replace cmail, and I want to move the local mailboxes from the workstations to the central server.
I can then shutdown the NT server

That isn't going to be very difficult.
Build the SBS server, including all the accounts, lists etc, so that it is ready to go.
Then stop the old server from collecting email (various ways of doing that - if you cannot see how to actually stop it, then change the POP3 server to localhost or something like that).
Use the POP3 connector on the SBS Server to collect email from your ISP.

On each of the clients, collect the email so that the old server doesn't have any email waiting to be collected.

Then add all of your workstations to the SBS domain.
Import the contents of the Outlook PST files in to each user's mailbox. Outlook can do this for you using the import wizard.

Then the only thing left to do is get your MX records changed to deliver email to the SBS server directly - which is how Exchange is designed to work. The POP3 connector is to help the move only - not designed as a long term solution.
