Verify Your Office 2021 Lifetime License and Support Lifecycle
Check your Microsoft account to confirm your perpetual license status and prepare for the official end-of-support date.
Microsoft Office 2021 is sold as a one-time purchase. This grants you a perpetual, lifetime license, meaning the software itself will never expire and can be used indefinitely on the licensed device.
However, this version does not receive new feature updates. Furthermore, Microsoft will officially end mainstream support for Office 2021 on October 13, 2026, after which no security or bug fixes will be issued.
Open any Office 2021 application such as Microsoft Word. Click on the 'File' tab in the top left corner, then select 'Account' from the bottom left menu to view your exact product activation and one-time purchase details.
Acknowledge that while the software will continue to open and function after October 13, 2026, you will need to plan for a future software transition to maintain system security against emerging vulnerabilities.
Navigate to the official Microsoft Store in your web browser to compare your current perpetual license with newer offerings. Note that upgrading to a newer major release of Office will require purchasing a new license at full price.

Frequently Asked Questions
Can I still use Microsoft Office 2021 after October 13, 2026?
Yes. Office 2021 is a one-time purchase with a lifetime license, meaning it will never stop functioning. However, after October 13, 2026, Microsoft will cease providing software updates, security patches, and technical support.
Does Office 2021 include a free upgrade to the next major version?
No. Because Office 2021 is sold as a perpetual, one-time purchase, it does not include upgrade rights. If you wish to upgrade to a newer major release in the future, you will have to pay full price for the new version.
What is the difference between Office 2021 and Microsoft 365?
Office 2021 is a one-time purchase that you can use indefinitely without paying recurring fees, but it receives no new features. Microsoft 365 is a subscription service that requires monthly or annual payments but guarantees you always have the most up-to-date features and security updates.
Why is my Office 2021 failing to work properly on Windows 11?
Office 2021 is fully compatible with Windows 11. If you are experiencing crashes or activation errors, it may be due to outdated system drivers or corrupted installation files. Try running the Windows Program Compatibility Troubleshooter or completely reinstalling the Office software.
