Understanding OneNote Version Changes

Learn how Microsoft updated the naming and functionality of the classic OneNote desktop application.

The primary difference lies in the naming convention rather than the software being a completely different program. OneNote 2016 was the classic desktop version included with Office 2016.

In 2019, Microsoft dropped the year from the name. The application is now simply called "OneNote." It continues to receive updates and is the default version included with Microsoft 365 and Office 2021 subscriptions.

1
Open the Windows Start Menu

Click the Start button on your Windows 10 or Windows 11 taskbar.

2
Search for OneNote

Type "OneNote" into the search bar. If you see an app named just "OneNote", this is the updated continuation of OneNote 2016.

3
Verify your account and version

Open the "OneNote" application, click on "File" in the top left corner, and select "Account" to view your current build and license information.

Understanding OneNote Version Changes

Frequently Asked Questions

Does Microsoft 365 include OneNote 2021?

Microsoft 365 includes the unified desktop application simply named "OneNote". It does not use the "2021" year designation, but it contains all the latest features and updates.

Can I still run OneNote 2016 on Windows 11?

Yes. The desktop app originally known as OneNote 2016 (now called OneNote) is fully supported on Windows 11 and continues to receive security and feature updates.

Why does my app just say "OneNote" without a year?

In 2019, Microsoft decided to drop the year from the application's name. If your app is just called "OneNote", you are using the primary, most up-to-date desktop version.

What will happen to OneNote for Windows 10?

Microsoft is consolidating its OneNote apps. OneNote for Windows 10 is no longer receiving new features and users are encouraged to migrate to the main "OneNote" desktop application.
