Microsoft 365 apps on Windows 10 to get security updates until 2028

Microsoft 365 apps for Windows 10 will continue to get security updates until Oct. 10, 2028, three years after the company ends support for Windows 10 this coming Oct. 14, Microsoft said in a blog post.

At the same time, the company noted that the apps could experience performance issues over time when running on Windows 10. If a customer contacts support about a problem with an M365 app for Windows 10 that does not occur on Windows 11, the customer will be told to upgrade to Windows 11.

If the user can’t do so, support will then only assist in troubleshooting the problem. Technical solutions might be limited — or not available at all. And it will not be possible to report bugs or request other product updates.

The extension of M365 support is a change from Microsoft’s plans in January, when it said support would end in October 2025.
