Summary:
Office 2016 and Office 2019 support will end on October 14, 2025. It is recommended to upgrade to Microsoft 365 E3 or Office LTSC 2024 for continued updates and support. Resources like upgrade guidance, Microsoft FastTrack, and the Office End of Support Tech Community are available to assist with the transition.
Details:
Support for Office 2016 and Office 2019 will end one year from today, on October 14, 2025. After that date, no further updates, security fixes, or technical support will be available for these versions of Office. While the applications may continue to function, using unsupported software could lead to potential security risks and other issues. Because migrations can take time, we recommend starting to upgrade any remaining devices your organization has running Office 2016 or Office 2019 to a supported version as soon as possible.
