Question details

The user needs a way to access and manage two different OneNote accounts, such as university and work profiles, at the same time on a Mac.

How to Use Two OneNote Accounts at the Same Time on Mac

Product: Microsoft OneNote
Device & OS: Mac
Scenario: Attempting to access notebooks from two separate organizations concurrently for school and work productivity.
Observed behavior: The OneNote Mac app does not natively support running multiple accounts simultaneously in the same way Teams does, causing notebooks to open under the wrong account and failing to display ownership clearly.

Before you start

Ensure you have the login credentials for both your work and university Microsoft accounts readily available, and verify that your default web browser is updated.

Solution 1Recommended

Use the Desktop App and a Web Browser Simultaneously

The most effective workaround to view two accounts at once on Mac without constantly signing in and out.

Since the OneNote desktop application for Mac restricts active sessions to a single primary account, leveraging a web browser for your secondary account is the best way to achieve simultaneous access.

Sign into the Mac App

Open the OneNote desktop app on your Mac and sign in with your primary account (e.g., your work account).

Open a Web Browser

Launch Safari, Google Chrome, or your preferred web browser.

Sign into OneNote Online

Navigate to the official OneNote website, click sign in, and enter the credentials for your secondary account (e.g., your university account). You can now view both accounts side-by-side.

Use the Desktop App and a Web Browser Simultaneously

Use Incognito Mode for More Accounts: If you need to access a third account concurrently, you can open a Private or Incognito window in your browser to sign in without logging out of your second account.

Solution 2

Sign Out and Switch Accounts Manually

If you prefer using only the native Mac application for offline capabilities, you will need to manually switch between your accounts.

Frequently Asked Questions

Why do my OneNote notebooks open under the wrong account on Mac?

This happens because the OneNote Mac app does not cleanly separate notebook ownership when multiple accounts have been linked in the past, often defaulting to the primary signed-in account credentials stored in your Mac's keychain.

Will Microsoft add multi-account support to OneNote for Mac like in Teams?

Microsoft continually updates its applications based on user demand, but there is no official timeline. You can submit a feature request at the Microsoft Feedback Portal to encourage them to implement true multi-account support.

Can I use different macOS user profiles to separate OneNote accounts?

Yes, creating a separate macOS user account for work and school allows you to sign into different OneNote accounts on each Mac profile, keeping the app data and login credentials completely isolated.
