Updates for Exchange Server

Exchange follows a quarterly delivery model to release Cumulative Updates (CUs) that address customer-reported issues and to possibly add new functionality and/or features. Critical product updates (packages that address a Microsoft-released security bulletin or contain a change in time zone definitions) are released as needed on a monthly basis for the most recently released CU and the preceeding CU.

Because each CU is a full installation of Exchange that includes updates and changes from all previous CU's, you don't need to install any previously released CU's when installing a new Exchange server using the latest released CU.

For information about the new features you'll get when you upgrade to Exchange 2019 from previous versions of Exchange, see What's new in Exchange Server.

To get the latest version of Exchange 2016, download and install Cumulative Update 10 for Exchange Server 2016. Because each CU is a full installation of Exchange that includes updates and changes from all previous CU's, you don't need to install any previous CU's or Exchange 2016 RTM first.

The following table contains links to Exchange Team blog posts ("What's New" information) for this and other Exchange 2016 CUs.
