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.
For additional information on Windows NT Server Client Access Licenses, please see the following article in the Microsoft Knowledge Base:
