Microsoft released Office 2019 two years ago on September 24, 2018. The new version of Office was released exclusively for Windows 10 and Mac OS X and included a number of fundamental changes to previous versions of Office and Office 365 (now Microsoft 365).
Office 2019 was released as a standalone version that required a one-time payment and no subscription. Customers could use Office 2019 on devices without Internet connection, and Microsoft aligned the support period with that of Office 2016. Both products will run out of support in 2025.
