Office 2021 keys: Professional Plus and more
An Office 2021 key gives you a complete suite as a one-time purchase: Word, Excel, PowerPoint and Outlook, plus Access and Publisher in the Professional and Professional Plus editions. Office 2021 brought XLOOKUP, dynamic arrays and real-time co-authoring. Microsoft support for Office 2021 ended in October 2026: the suite keeps working with no time limit, without new security updates. Prices start at €19.90; see our Office 2021 key guide, or our 5-PC licenses to equip several computers.

Why is Office 2021 still popular?
It introduced the Excel functions that changed daily work: XLOOKUP, which replaces VLOOKUP, plus FILTER, SORT, UNIQUE and LET. It also brought real-time co-authoring, dark mode and a cleaner interface. For classic office work, it does everything most users need from a desktop suite.
Office 2021 or Office 2024?
The feature gap is small. What really separates them is support: Microsoft stopped updating Office 2021 in October 2026, while Office 2024 is supported until October 2029. If you plan to keep the suite on a connected PC for several years, Office 2024 is the safer choice. Read our Office 2021 vs 2024 comparison.
Are Office 2021 files compatible with newer versions?
Yes. Office 2021 opens and saves the same .docx, .xlsx and .pptx formats as Office 2024 and Microsoft 365. A file sent by a colleague using a newer version opens normally, unless it relies on an Excel function introduced after 2021, which then shows an error in the affected cells.
How is my Office 2021 key delivered?
By email, usually within a few minutes of payment, with the official download link and activation steps for Windows 10 or Windows 11. A VAT invoice is issued for every order. If a key ever proves defective we replace it for life, and our support team replies by email 7 days a week within 24 hours.
