SUMMARY
=======
Any user who wants to access information on a computer running Microsoft
Exchange Server requires a Client Access License (CAL) for Exchange. However,
not all users of Microsoft Exchange clients require a Windows NT Server Client
Access License (CAL).
MORE INFORMATION
================
How to determine if you need a Windows NT Server CAL.
If your client uses Windows NT Server for any of these basic networking features,
a Windows NT Server CAL is required:
File Sharing
Printer Sharing
Remote Access Services
Mac Services
If your Exchange Client user is not using any of the above networking features of
Windows NT Server, a Windows NT Server CAL is not required. If you use Windows
NT Server strictly as an application server (that is, just to run Exchange) does
not require a Windows NT Server CAL.
