Microsoft Announces End of Support for Office 2016 and 2019 in October 2025

Microsoft has officially announced that it will discontinue support for all applications within the Office 2016 and 2019 suites, including popular programs such as Excel, Word, and PowerPoint, effective October 14, 2025. The same cessation date applies to Windows 10 support. Post October 2025, Microsoft will no longer provide new features, updates, security patches, or customer support for these versions. The discontinuation is anticipated to pose potential security risks, productivity declines, and compatibility problems for users who continue using the outdated software. To mitigate these issues, Microsoft recommends transitioning to the Microsoft 365 E3 cloud suite, which provides similar functionalities.
