GoKawiilMicrosoft Office 2019 and 2021 for Mac view-only conversion (2026) is a scheduled remote degradation of perpetually-licensed Microsoft Office software for macOS and iOS, set for July 13, 2026 when a license-validation certificate used by the Office apps expires.[1] After Office 2019 for Mac reached end of support in October 2023, Microsoft assured customers their installed apps would "continue to function."[2] The July 13, 2026 conversion instead drops the apps into a Microsoft-defined "reduced functionality mode," in which files can be opened and viewed but not edited or saved.[1][3] By May 30, 2026, the original 2023 end-of-support page had been re-dated and rewritten on Microsoft's site; the "continue to function" clause was removed.[4][2]
Microsoft announced general availability of Office 2019 for Windows and Mac on September 24, 2018. In the launch blog post, Microsoft's Jared Spataro wrote that "Office 2019 is a one-time release and won't receive future feature updates," positioning the product as the on-premises alternative to the Office 365 subscription.[5] Contemporary Microsoft Store pages marketed Office Home & Student 2019 as a "One-time purchase for 1 PC or Mac" at $149.99, with copy that explicitly contrasted the perpetual product against the Office 365 subscription model: "One-time purchases don't have an upgrade option, which means if you plan to upgrade to the next major release, you'll have to buy it at full price."[6]
Office 2021 for Mac became generally available on October 5, 2021 under the same one-time-purchase model & is scheduled to reach end of support on October 13, 2026 per the Microsoft Lifecycle Policy.[7]
Office 2019 for Mac reached end of support on October 10, 2023.[3]

The June 3, 2023 snapshot of Microsoft's end-of-support page contained this passage:
Support for Office 2019 for Mac will end on October 10, 2023. Rest assured that all your Office 2019 apps will continue to function—they won't disappear from your Mac, nor will you lose any data. However, you could expose yourself to serious and potentially harmful security risks.[2]
