A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Use the same school account in the Mac app that opens the notebook on the web, then reset the app sign-in state if the Mac app keeps rejecting it.
- In OneNote for Mac, sign out of the current account:
- Menu bar: OneNote > Sign Out.
- Sign back in with the school account that can open the notebook in the browser:
- Menu bar: OneNote > Sign In.
- If the notebook is tied to a different account than the one currently active, switch accounts and sign in with the account that actually contains the notebook.
- Verify access in the browser:
- Sign in to OneNote for the web with the same school account.
- If the notebook opens there, go to OneDrive with that same account, open the notebook in the browser, then click Open In OneNote. If prompted, sign in in the Mac app with that same account.
- If the Mac app still repeatedly asks for sign-in or rejects the school account:
- Update OneNote for Mac to the latest version.
- Sign out of all accounts associated with OneNote, then sign in again.
- If repeated sign-in prompts continue on macOS, clear the stored Office credentials:
- Quit all Mac Office apps except OneNote.
- In OneNote, sign out.
- Quit OneNote.
- Open Keychain Access and search for items containing Office15.
- Delete the items whose kind starts with MicrosoftOffice15.
- Open OneNote and sign in again.
Notes:
- OneNote for Mac requires signing in with a Microsoft account or the work or school account provided by the organization.
- If the school notebook opens on the web but not in the app, the issue is commonly the saved account/credential state in the Mac app.
- Clearing credentials removes authentication data only. Office apps that share those credentials may require sign-in again.
