Brief Lesson on Exchange Licensing

Understand Exchange's per-server vs. per-user licensing implications and you'll save money down the road.

Bill: I'm about to upgrade our seven-year-old Macintosh e-mail server to a Windows 2000-based Exchange server. We'll primarily be using the Exchange server as a POP server but would also like to have a server-based address book.

Based on these specs, is it necessary to purchase client licenses for each computer that will have a POP account set up and that will use the public
address book?

Joshua: The license agreement for Exchange 2000 states that you must have a CAL for any user who gains access to Exchange services. This includes POP3, IMAP4, and OWA connections along with standard Outlook clients.

Exchange 2000 has a per-server license and a per-user license. You should opt for the per-user license so that you can set up a second server in the future, if necessary. With per-user licensing, you'll need 1,000 CALs if you have a thousand users with accounts on the Exchange server.

Exchange 2003 has a per-device CAL so that multiple users can access the Exchange server via a kiosk machine and take only a single CAL. You can purchase a mix of per-device and per-user CALs for the same Exchange organization, but the License Service does not know how to differentiate between them so you have to keep pretty careful records.
