The Exchange 2003 device CAL is required for each device accessing the server and entitles access rights to an unlimited number of users sharing this common device. An example of such a device is a kiosk running Outlook Web Access that is shared by several e-mail users.
To compete successfully in today's challenging business climate, organizations must enable more efficient ways for information workers to communicate and collaborate. E-mail is currently the most widely used collaborative technology. More businesses use Exchange for e-mail-based collaboration than any other product. Exchange 2003 enables information workers to gain access to critical business communications almost whenever and wherever they need to and is designed to deliver greater security, availability, and reliability. Exchange 2003 sets a new benchmark for low total cost of ownership (TCO) by helping your information technology (IT) staff to do more with less through improved management tools.
