Buy a genuine Microsoft Office 2021 license key with instant email delivery. One-time purchase, perpetual license — no subscription required.
Office 2021 was Microsoft's last major perpetual-license release before Office 2024, and it remains one of the most widely used versions in homes and small businesses. It includes Word, Excel, PowerPoint, and Outlook, with Access and Publisher added in Professional Plus on Windows. Every key we sell is a genuine one-time-purchase license — install it once and it's yours, with no recurring subscription fee.
Home & Business covers Word, Excel, PowerPoint, Outlook, and OneNote — the apps most personal and small-business users need.
Professional Plus adds Access (database) and Publisher (desktop publishing) on Windows, aimed at users who need those extra tools alongside the core apps.
Office 2021 is also available for Mac, with the app set matched to what's supported on macOS.
If you don't need the newest interface changes, Office 2021 is a proven, stable release that costs less than the current version while still being fully supported and fully genuine. It's a solid choice if you want the classic Office experience without paying for the latest release.
If your key doesn't activate, we'll replace it or refund you under our 180-day guarantee.
