For more information, see the Licensing section below.
Licensing Below are some of the major licensing requirements for Exchange Server. For each server software license you assign, you may run, at any one time, one instance of the server software in one physical or virtual operating system environment on the licensed server. You may run or otherwise use any number of instances of the Exchange Management Tools software in physical or virtual operating system environments on any number of devices.
You may use those instances only with the server software. Use of any instance with the server software may be direct, indirect, or through other additional software. Exchange Server is a server application, not a server operating system, so it must be used along with a server operating system.
For each instance of Exchange Server, you must also have a Windows Server license. However, you do not need CALs for Up to two devices or users to access the server software only to administer those instances Any user or device that accesses your instances of the server software without being directly or indirectly authenticated by Active Directory Standard CALs For both the Standard and Enterprise editions of Exchange Server, the Standard device or user CALs authorize one user or device to access Exchange Server.
These features include integrated archiving, in-place hold, data loss prevention, and unified messaging features. For a complete list, see the Exchange Server Licensing page Enterprise CALs do not need to be requested for users or devices that do not need to access these additional features. You can use Software Assurance to upgrade Exchange Server and associated licenses to any version released during the two years your Software Assurance is in effect.
The actual upgrade does not have to take place within those two years. You can upgrade at any time in the future, as long as Microsoft still makes the new version available to users.
You cannot, however, upgrade to versions that Microsoft releases after your Software Assurance expires. Downgrading You can downgrade Exchange Server to any version that Microsoft continues to make available at its Volume Licensing Service Center website on your organization's Licensed Downloads page.
Downgrading does not depend on Software Assurance; it is a benefit of Volume Licensing. CALs obtained through TechSoup will work with the downgraded version. Related Content.
