How to Install Microsoft OneNote on Linux: Web and Snap Options

Microsoft does not offer a native OneNote desktop installer for Linux. The supported way to use Microsoft OneNote on Linux is in a modern browser at OneNote for the web. You can keep it in a browser tab, install a Chrome shortcut that opens in its own window, or try P3X OneNote, an unofficial Linux client maintained by a third party.

Use the official OneNote web app

This option needs no Linux package and works with a personal Microsoft account or a work or school account. Microsoft describes OneNote for the web as a way to open and edit cloud notebooks from a modern browser on different operating systems.

1. Open onenote.com in an up-to-date browser.
2. Select Sign in and use the account that owns or has access to your notebook. If your organization manages the notebook, use its work or school account.
3. Choose a notebook from the notebook list. To make a new one, open the notebook list at the upper left, choose Add Notebook, enter a name, and select Create Notebook.

New notebooks are stored online, typically in OneDrive for a personal account or in your organization’s Microsoft 365 storage. OneNote for the web saves changes automatically, so there is no Save button. Keep an internet connection while you work and confirm that you are in the correct account if a notebook is missing.

Install OneNote as a Chrome app window

Chrome can install a website as a web app on Linux. This adds a launcher entry and opens OneNote in a separate window; it does not install Microsoft’s Windows desktop software or add its extra features.

1. Open OneNote in Chrome and sign in.
2. Open Chrome’s menu, choose Cast, save, and share, then choose Install page as app.... Some pages also show an install icon in the address bar.
3. Follow the confirmation prompt. Start OneNote later from the Linux application menu. If you use multiple Chrome profiles, install it in the profile where you want the account session saved.

Optional: install the unofficial P3X OneNote package

If you want an installable Linux package instead of a browser shortcut, the P3X OneNote project publishes an Electron-based client. It is a community project, not software made or supported by Microsoft, so review its source repository before signing in. The Snap Store listing currently uses the package name p3x-onenote.

1. Make sure snapd is installed and enabled for your distribution. Use Snapcraft’s setup instructions if you need to add Snap support.
2. Open a terminal and run:

sudo snap install p3x-onenote

After installation, launch P3X OneNote from your desktop’s application menu. For another package format, use the project’s current GitHub Releases page and choose a Linux asset that matches your distribution and processor architecture. Do not reuse the old, version-pinned AppImage links from older tutorials.

Know the web version’s limits

OneNote for the web is convenient for everyday typing, organizing, and sharing, but it is not identical to the desktop client. Microsoft documents differences in features such as ink and equations, audio and video, shapes, and Outlook integration. Check the browser-versus-desktop feature list if your workflow depends on one of those tools. Installing the Chrome shortcut does not change these limits or guarantee offline access.

Fix common setup problems

• Your notebook is missing: sign out and check whether it belongs to a different personal or work account. Ask your organization for access if it is stored in a managed SharePoint or OneDrive location.
• The page will not let you type: you may be in Reading view. Use Edit Notebook and then Edit in OneNote for the web.
• Changes do not appear on another device: leave the browser online for syncing, then reopen the notebook. OneNote for the web saves continuously, but it still needs to sync with its cloud storage.

For most Linux users, start with OneNote for the web and add the Chrome app shortcut if you want a dedicated window. Choose P3X only if you specifically prefer a third-party Linux package and are comfortable relying on an independently maintained client.
