Frequently Asked Questions

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 and the exact version and build number.

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 while your subscription is active.

Your apps keep working, but Microsoft stops security updates, bug fixes and technical support. Running unsupported software is a security risk, so upgrading is recommended.

The version (e.g. “Version 2406”) tells you the release cadence; the build number identifies the exact update installed. Both are shown under File > Account > About.
