About this licence
Office Home & Business 2021 is the step-down choice for a small business that needs Outlook but does not need the 2024 features. You get Word, Excel, PowerPoint, OneNote and Outlook on one Windows PC with commercial use allowed, and Microsoft keeps patching it until October 2026.
The 2021 wave introduced XLOOKUP, dynamic arrays and co-authoring that still feel modern today, so for most offices the difference from 2024 is cosmetic. Because the price sits well below the current edition, it is a sensible way to equip a second machine or to match the version colleagues already run. Activation uses the same Microsoft-account flow as every retail Office key.

- Licensed for commercial use
- XLOOKUP, dynamic arrays and the 2021 Outlook

Dates are Microsoft's published lifecycle dates. "Security updates until" is the date after which Microsoft stops patching that version; the software keeps activating and working after it.
