About this tag
Office 2021 is a perpetual version of Microsoft's productivity suite that reaches end of support on October 13, 2026. After that date, Office 2021 apps will continue to run, but Microsoft will stop providing security updates, bug fixes, technical support, and extended security updates. This leaves users and IT administrators responsible for managing any new vulnerabilities. The tag covers the end-of-support timeline, upgrade options such as moving to Office 2024 or alternatives like LibreOffice, and practical considerations for staying on Office 2021 temporarily. It also touches on related issues like Excel problems and feature cutoffs for older Office versions, helping users plan their next steps.
