Microsoft Exchange Server 2010 DEVICE CAL

Each user or device accessing the Exchange Server requires an access license (CAL). The CALs are available in the variants User CAL (for access by a licensed user) and Device CAL (for access by a licensed device). With the corresponding CAL, the user (User CAL)/device (Device CAL) can access all Exchange servers within the domain. The functionality of the Exchange server is determined by the type of CAL.
