Important: Office 2021 support ends on 13 October 2026.
After that date Microsoft stops all security updates, bug fixes and technical support for Office 2021. Unlike Windows 10, there is no extension and no paid Extended Security Updates programme. The apps keep working, but any vulnerability found afterwards stays unpatched permanently.
If you want a perpetual licence that stays supported, choose Office 2024 Professional Plus instead — it is supported until October 2029.
Microsoft Office 2021 Professional Plus – Lifetime License
Includes Word, Excel, PowerPoint, Outlook, Access, Publisher and OneNote. Perpetual licence, one-time purchase, no subscription. Compatible with Windows 10 and Windows 11 (64-bit).
Who this is still right for
Office 2021 remains a sensible buy if you need a low-cost perpetual licence for a short-term need, work mostly with local files, and do not open untrusted attachments. If the machine handles client data, contracts or financial records, choose Office 2024.
System Requirements
- OS: Windows 10 or Windows 11 (64-bit)
- RAM: 4 GB
- Storage: 4 GB
Frequently Asked Questions
When exactly does Office 2021 support end?
13 October 2026. Microsoft has confirmed there will be no extension and no Extended Security Updates programme for Office 2021, unlike Windows 10. After that date there are no more security patches, bug fixes or technical support.
Will Office 2021 stop working after October 2026?
No. Your licence does not expire and the apps keep opening and saving documents normally. What stops is the supply of security updates, so newly discovered flaws in Word, Excel, Outlook or PowerPoint remain permanently unpatched.
Should I buy Office 2021 or Office 2024?
Office 2024 is supported until October 2029 and is the better value over any horizon longer than a few months. Office 2021 makes sense only if the price difference matters and the support window is enough for your needs.
Does Office 2021 Pro Plus include Access and Publisher?
Yes. The Professional Plus edition includes Word, Excel, PowerPoint, Outlook, Access, Publisher and OneNote. Note that Publisher is also being retired by Microsoft on 13 October 2026 and is not included in Office 2024.
How do I activate Office 2021 after purchase?
After receiving your key by email, download Office from Microsoft's official website, install it, and enter your product key when prompted. Activation takes less than 5 minutes.
Can I use Office 2021 without an internet connection?
Yes. After activation, Office 2021 works fully offline. An internet connection is only needed for the initial activation and optional cloud features like OneDrive sync.
