Office 2021 Standard

Office 2021 LTSC Standard for Windows is the volume-license edition of Office for companies, with Word, Excel, PowerPoint, Outlook, OneNote and Publisher on one PC.

This edition covers everyday office work: correspondence and reports in Word, calculations in Excel, presentations in PowerPoint, and email and appointments in Outlook. OneNote collects meeting notes and ideas, and Publisher creates flyers, newsletters and print material. Commercial use is permitted.

Who is this edition for?

• Companies that need a fixed feature set without ongoing feature updates, for example in regulated or restricted environments.
• Offices with typical document, spreadsheet and email work that don't need an Access database.
• Businesses that want the classic Office desktop apps, including Outlook and Publisher, on one PC without a subscription.

The apps at a glance

• Word 2021: letters, quotes, reports and contracts. Dark Mode now also turns the page itself dark, and Line Focus guides you through long texts line by line.
• Excel 2021: calculations, analyses and reports. XLOOKUP, LET and dynamic arrays with FILTER, SORT and UNIQUE replace complicated nested formulas.
• PowerPoint 2021: presentations for customers and meetings. Record Slide Show now also captures presenter video, ink and laser pointer.
• Outlook 2021: email, calendar and contacts. Translator translates messages into more than 70 languages, and Instant Search finds emails anywhere in Outlook.
• OneNote: your digital notebook for meeting notes, ideas and checklists.
• Publisher 2021: design flyers, newsletters and print layouts with ready-made templates.

What's new in Office 2021 for Windows?

Office 2021 Standard is an LTSC edition (Long Term Servicing Channel) with a fixed feature set. Word, Excel and PowerPoint now support the OpenDocument Format (ODF) 1.3, Excel unhides several hidden sheets at once, and PowerPoint replays ink drawings as an animation. Real-time co-authoring, modern comments and the visual refresh are not part of the LTSC edition.

Buy once, use permanently

Office 2021 Standard is a one-time purchase: no monthly or yearly fees, and after activation you can also work offline. It is installed with Microsoft's free Office Deployment Tool and activated with the product key. Microsoft ended support for this version on October 13, 2026: the apps keep working, but they no longer receive security updates. New features, cloud storage and Copilot come only with a Microsoft 365 subscription. An older version makes sense when templates, macros or add-ins are tied to it or when a specific software requires it. Office 2021 runs on Windows 11 and Windows 10 (32-bit or 64-bit) with 4 GB RAM and 4 GB of free disk space.

Office 2021 Standard or another edition?

For security updates until 2029, choose Office 2024 Standard for Windows. If you also need Access, take Office 2021 Professional Plus for Windows.
