Office 2021 End of Life: What to Do

Microsoft ended support for Office 2021 on 13 October 2026. The apps keep working, but Microsoft no longer issues security or feature updates.

What changes

• No more security updates, so new vulnerabilities stay unpatched.
• No more bug fixes or technical support from Microsoft.
• Your files still open, and the apps still run.

Is it safe to keep using Office 2021?

It still works, but it is riskier over time, especially for email and files from outside. For work use or sensitive data, moving to a supported version is the safer choice.

Your options

1. Office 2024: a one-time purchase with support until October 2029. See Office 2024 in Malaysia.
2. Microsoft 365: a subscription with continuous updates. Compare in Office 2024 vs Office 2021 vs Microsoft 365.
3. Stay on Office 2021: acceptable for offline, low-risk use.
