XGEN: When Do Exchange Users Need a Client Access License (CAL)?

ID: Q168633


The information in this article applies to:


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.
