This includes Exchange Server, as well as Microsoft Office, SharePoint Server, Office Communications Server, Lync Server, Skype for Business Server, Project Server, and Visio. Furthermore, as adoption of Microsoft 365 or Office 365 accelerates and cloud usage increases, custom support options for Office products will not be available. There will be no new security updates, non-security updates, free or paid assisted support options, or online technical content updates. Exchange Server 2007 End-of lifeĮxchange 2007 reached end of support on April 11, 2017, per the Microsoft Lifecycle Policy. For more information about the Microsoft Support Lifecycle, see the Microsoft Support Lifecycle Policy FAQ. Support lifecycleįor more information about the support lifecycle for specific versions of Exchange, Windows Server, or Windows client operating systems, see the Microsoft Support Lifecycle page. Security Updates (SUs) delivered separatelyĪt this time, no additional CUs are planned for Exchange Server 2013 and Exchange Server 2016.

For more information, see Updates for Exchange Server. Each CU is a full installation of Exchange that includes updates and changes from all previous CUs, so you don't need to install any previous CUs or Exchange Server RTM first. In this model, cumulative updates (CUs) are released quarterly (every three months). In Exchange Server 2013 or later, we changed the way we deliver hotfixes and service packs by using a scheduled delivery model.

For more information, see Exchange 2010 Servicing. The updated files that are included in an individual update or hotfix include all updates that were applied only to those specific files by all previous updates, but any other files on Exchange Server will not be updated. However, individual updates or hotfixes for Exchange 2010 or earlier do not contain all previous fixes for Exchange Server. An RU for Exchange Server 2010 includes all fixes for Exchange Server from all previous update rollup packages, so you only need to install the latest RU to apply all of the fixes that were released up to that point. In Exchange Server 2010 and earlier, each update rollup package (RU) is cumulative. The following table identifies the release model for each supported version of Exchange. The Exchange Server supportability matrix provides a central source for Exchange administrators to easily locate information about the level of support available for any configuration or required component for supported versions of Microsoft Exchange Server.
