An Exchange Server Enterprise user client access license (CAL) can be used only in conjunction with an Exchange Server Standard user CAL. It authorizes one user to access additional features in Exchange Server Standard or Enterprise edition on any number of computers or other devices. For example, an employee might access the server from a computer at work and another at home. This offer provides one Enterprise user CAL. Enterprise device CALs — for providing devices with access to additional features — and Standard CALs (user and device) are also available. Major Capabilities The Enterprise CAL provides access to the following additional features in Exchange Server Standard or Enterprise edition.

An Exchange Server Standard user client access license (CAL) authorizes one user to access Exchange Server Standard or Enterprise edition from any device. For example, an employee might access the server from a computer at work and another at home. This offer provides one Standard user CAL. Standard device CALs for licensing computers and additive Enterprise CALs (user and device) for accessing additional features are also available. Additional Information For additional information about Exchange Server and the server and client licensing requirements, see the Guide to Exchange Server Editions and Licensing.

A Project Server user client access license (CAL) authorizes a user to access the services of Project Server from any device (for example, when an employee accesses the server from a computer at work and another at home). Any application that accesses the services of Project Server requires a CAL, including Project Professional, Project Web App, SharePoint sites with Web Parts that display project information, Microsoft Office Outlook integration, and third-party applications. This offer provides one user CAL. Device CALs for licensing computers are also available. License Only CALs, ECLs, and management licenses (MLs) offered through Connecting Up are always for the currently offered version of the server software. However, these licenses can also be used with earlier versions of the server software.

Windows Server is Microsoft's solution for workgroup file, print, and communication servers, as well as for Internet content delivery. A device client access license (CAL) is needed for every device accessing Windows Server for file services, printing services, remote access service, or terminal services. It is also needed for any authenticated devices accessing Windows Server as a web server or an application server. This offer provides one device CAL that authorizes one computer to access Windows Server, regardless of the number of users (for example, on a shared workstation). User CALs for licensing individuals and external connector licenses (ECLs) for licensing a significant number of external users are also available.
