Frequently Asked Questions

How do I find out which version of Microsoft Office I have?

Open any Office app (like Word or Excel), go to File > Account (on Windows) or the app menu > About (on Mac). You'll see the product name (for example, 'Microsoft 365' or 'Office Professional Plus 2021') and the exact version and build number.

Is my version of Office still supported?

Microsoft supports each one-time-purchase version of Office for a fixed period. Office 2016 and 2019 reached end of support on October 14, 2025. Office 2021 is supported until October 13, 2026, and Office 2024 until October 9, 2029. Microsoft 365 stays supported as long as your subscription is active.

What happens when my Office version is no longer supported?

Your Office apps keep working, but Microsoft stops providing security updates, bug fixes, and technical support. Running unsupported software is a security risk, so it's a good idea to upgrade to a supported version.

What's the difference between the version and the build number?

The version (for example, 'Version 2406') tells you the release cadence, while the build number (for example, '16.0.17726.20126') identifies the exact update installed. Both are shown under File > Account > About.
