Microsoft Ends Office 2021 Support on Oct. 13, 2026, Pushing Users to Microsoft 365

3 articles · Updated · XDA Developers · Jun 20

Summary

  • Oct. 13, 2026 is the cutoff for Office 2021 support, after which Microsoft will stop security patches, bug fixes and technical assistance while the software itself remains usable.
  • Microsoft's updated guidance warns users will also lose phone and chat support, software updates and most online help content once the suite reaches end of life.
  • Security is the main pressure point: the company says newly discovered vulnerabilities after the deadline will go unpatched, raising risks for users who stay on the one-time-purchase version.
  • Microsoft is steering customers toward Microsoft 365, while also offering Office 2024 as a non-subscription upgrade or leaving users to consider rival productivity suites.
