• Exchange Server 2013 licensing

    Learn about your options for licensing Exchange Server 2013. For information about prerequisites for licenses, see Exchange Server 2013 Prerequisites.

    Server licenses

    With this license type, a license must be assigned for each instance of the server software that is being run. There are two server editions:
    • Standard: designed for the mailbox needs of small to midsize organizations. Also appropriate for non-mailbox roles in a larger Exchange deployment. This edition supports 1 to 5 mailbox databases.
    • Enterprise: designed for larger organizations that may require a greater number of mailbox databases. This edition supports 1 to 100 mailbox databases. (To use 100 mailbox databases you must have installed Exchange Server 2013 RTM Cumulative Update 2. Learn more.)

    CALs

    With this license type, a CAL is required for each user or device that accesses the server software. There are two types of CALs for Exchange, both of which work with either edition of the server:
    • Standard: designed to help users be more productive from virtually any platform, browser, or mobile device, with new features in Exchange Server 2013 that help manage communications overload and lower helpdesk costs. To enable Standard CAL features for a user, the user must be licensed with the Standard CAL.
    • Enterprise: designed to allow organizations to reduce the cost and complexity of meeting compliance requirements with new integrated archiving functionality and information protection capabilities, while also helping you cut costs by replacing legacy voice mail systems with Unified Messaging. The Enterprise CAL is sold as an add-on to the Standard CAL—to enable Enterprise CAL features, the user must be licensed with one Standard CAL plus one Enterprise CAL.

Note that if you buy either the Standard CAL or the Enterprise CAL without Services, you can also purchase Exchange Online Protection as a standalone plan. DLP services in Office 365 are not available as a standalone plan.
