Exchange Server

An Exchange Server Standard device client access license (CAL) authorizes one computer or other device to access Exchange Server Standard or Enterprise edition regardless of the number of users (for example, on a shared workstation). This offer provides one Standard device CAL. Standard user CALs for licensing individuals and additive Enterprise CALs (user and device) for accessing additional features are also available.
