About this tag
Office 2021 is a one-time purchase, perpetual version of Microsoft's office suite that includes classic desktop apps like Word, Excel, PowerPoint, Outlook, OneNote, and Publisher. Its end of support is scheduled for October 13, 2026, after which it will no longer receive security updates, bug fixes, or technical support from Microsoft. Discussions on WindowsForum cover upgrade planning, migration options to Office 2024 or Microsoft 365, security hardening for continued use after support ends, and the risks of discounted third-party bundles. Users also report specific issues like Excel cell selection problems and seek advice on safe purchasing from deal marketplaces.
