Microsoft Office 2019 (the Second perpetual release of Office 16) is a version of Microsoft Office for both Windows and Mac. It replaced Office 2016 and was replaced by Office 2021 on October 5, 2021. It was unveiled on April 27, 2018, for Windows 10 and June 12, 2018, for macOS, and launched on September 24, 2018. Some features that had previously been restricted to Office 365 subscribers are available in this release. Office 2019 remains same major version 16 as its predecessor Office 2016. Therefore it is the second perpetual release of Office 16. Microsoft plans to end mainstream support for Office 2019 on October 10, 2023. Unlike other versions of Microsoft Office, Office 2019 will only get two years of extended support, which means that support for Office 2019 will end on the same day as support for Office 2016, and Windows 10 will end on October 14, 2025.
