How can I determine the number of CAL's I need to buy for an Exchange 2007 installation? Is it the number of mailboxes?

Yes, I would talk to a Sales rep who can sale MS Exchange Cals to get a better understanding of your license needs.

A CAL is required for each user or device (depending on the license) accessing the server. Either version of the CAL may be run against either version of the server.

The CAL (client access license) is just a license that gives you one connection to the exchange server.  The can be either for Users, or for devices.  The good rule of thumb is have enough licenses for the maximum number of CONCURRENT connections.  You can find more information at:

If you have 50 users accessing the server and you buy per user, that would be 50 user CAL's required.
But, if you have 50 users accessing the server via 10 workstations, you could license per Device and buy 10.
