What is Microsoft OneNote?

Microsoft OneNote is a digital note-taking application from Microsoft. People use it to create notebooks, store text, images, drawings, meeting notes, web clippings, and other reference material, often synced through Microsoft accounts, OneDrive, or Microsoft 365. On a Mac, users commonly encounter it as a standard desktop app installed from the Mac App Store or Microsoft distribution channels.

Safety overview

Status: Safe

This is a legitimate Microsoft application. It is generally safe to keep installed, but removing the app or its data may affect access to locally cached notebooks, preferences, and offline content that has not fully synced.

Recommendation: Keep it if you actively use OneNote or rely on synced notebooks. Remove it if unused, but review whether any important notes or offline changes still need to sync before deleting related app data.
