Editing Microsoft Exchange Server (section)

==Licensing==
Like Windows Server products, Exchange Server requires [[client access license]]s, which are different from Windows CALs. Corporate license agreements, such as the [[EA/SA|Enterprise Agreement]], or EA, include Exchange Server CALs. It also comes as part of the Core CAL. Just like Windows Server and other server products from Microsoft, there is the choice to use User CALs or Device CALs. Device CALs are assigned to devices (workstation, laptop or PDA), which may be used by one or more users.<ref>{{cite web |title=Top 75 Microsoft Licensing Terms – A Glossary From A(ntigen) To Z(une)|url=http://omtco.eu/references/microsoft/top-75-microsoft-licensing-terms-a-glossary-from-antigen-to-zune/|publisher=OMTCO, omt-co Operations Management Technology Consulting GmbH|access-date=April 24, 2013}}</ref> User CALs, are assigned to users, allowing them to access Exchange from any device. User and Device CALs have the same price, however, they cannot be used interchangeably.

For service providers looking to host Microsoft Exchange, there is a Service Provider License Agreement (SPLA) available whereby Microsoft receives a monthly service fee instead of traditional CALs. Two types of Exchange CAL are available: Exchange CAL Standard and Exchange CAL Enterprise. The Enterprise CAL is an add-on license to the Standard CAL.
