Onenote not showing all notebooks

OneNote not showing all notebooks usually comes from 4 causes: you’re signed into the wrong account, the notebook list is hidden, the notebook has not synced, or the cloud notebook was never opened on this device. Miss one check, and you can edit the wrong copy or miss recent changes. This guide maps each cause to the fastest fix.

Start with the account check, then open the navigation pane, then check sync status, then open the notebook from OneDrive or SharePoint if it exists online but not in the app. If the notebook is missing on a second laptop or an iPhone too, that clue matters.

Diagnosing why notebooks are missing from the list

What this symptom usually means

Missing notebooks usually point to a visibility problem, not a deleted notebook. The notebook may still exist online in OneDrive or SharePoint, but the app may be signed into a different Microsoft account, hiding the list, or showing an unsynced copy.

Say your work notebook appears on the web but not on a home laptop. That usually means an account mismatch or an unopened notebook, not content loss. Say the notebook title is visible but sections are missing. That is a different problem from a notebook that is missing from the list entirely.

How to tell a missing notebook from a missing section or page

1. If the notebook name is absent, check the notebook list or open command first.
2. If the notebook name is present but a section is missing, open the section list inside that notebook and check sync status.
3. If a page is missing, use All Notebooks search and search for an exact phrase in quotes.
4. If the content appears on one device but not another, compare the signed-in account on both devices.

Which device and app version to note first?

It is a common rule of thumb to write down the device, the OneNote version, and the account shown in the app before making changes. Microsoft recommends OneNote from Microsoft 365 on Windows over OneNote for Windows 10, and OneNote for Windows 10 reaches end of support in October 2025. The steps below differ by version.

Why are notebooks missing?

Missing notebooks most often come from the wrong Microsoft account or a hidden notebook list. Less commonly, the notebook exists online but has not been opened in the app, or the notebook is present but stuck behind a sync problem. The quickest fix depends on where the notebook disappears.

Wrong Microsoft account

1. In OneNote, open the account menu and check the email address shown there.
2. Compare that address with the account that owns or was invited to the notebook.
3. Sign out of the wrong account, then sign in with the account that has access.
4. Reopen the notebook list after signing in.

If the notebook is shared, the owner may have invited a different address. A common first-timer mistake is checking the notebook on a personal account on one laptop and a work account on another, then assuming the notebook vanished.

Hidden navigation pane

1. In desktop OneNote, select the Navigation button to show or hide the navigation pane.
2. Check whether the notebook list is hidden behind a collapsed pane.
3. If the pane is narrow, drag its edge to resize it until notebooks and sections are visible.
4. In OneNote for Windows 10, the notebook list dropdown is usually next to the current notebook name and can be used to reveal notebooks in the navigation pane.

The navigation pane can sometimes hide notebooks and sections behind a collapsed pane. That is why a notebook can appear missing when it is only collapsed.

Notebook not opened in the app

1. In OneNote for Microsoft 365, choose File > Open.
2. Look for the notebook in the cloud locations shown there, especially OneDrive or SharePoint.
3. Open the notebook from OneDrive or SharePoint if it is listed there.
4. Return to the notebook list and confirm it now appears.

If the notebook exists online but not in the app, opening it through File > Open is the fastest fix. This matters most for shared notebooks stored in OneDrive or SharePoint.

Sync problem or delayed sync

1. In desktop OneNote, open the notebook’s sync options and choose View Sync Status.
2. In the Shared Notebook Synchronization dialog box, choose Sync All.
3. For a single notebook, choose Sync Now.
4. Watch for any error text tied to that notebook or section group.

OneNote automatically synchronizes shared notebooks at regular intervals, and OneNote for Windows 10 automatically syncs all notes. If one device still shows old data, the notebook may be stuck on that device rather than missing from the account. (Microsoft Support)

Notebook troubleshooting matrix

This matrix separates the usual causes from the fastest check. It also shows where the fix differs between OneNote for Microsoft 365 and OneNote for Windows 10, and where a second laptop or iPhone points to an app-visibility issue rather than a deleted notebook.

Still not working?

If the notebook still does not appear, use All Notebooks search and search for an exact phrase in quotation marks. OneNote can search the entire contents of any notebook or all notebooks, which helps when the notebook is present but hard to spot. Then check whether the notebook was moved, renamed, or shared with a different account.

Use All Notebooks search

1. Open search in OneNote.
2. Select the All Notebooks scope.
3. Type a word or paste an exact phrase in quotation marks.
4. Open the result and confirm which notebook contains it.

Check whether the notebook moved or was shared elsewhere

1. Open the notebook link from OneDrive or SharePoint if you have it.
2. Compare the notebook owner and the signed-in account.
3. Look for the notebook under another Microsoft account on the same device.
4. If the notebook existed only as a shared notebook, confirm the sharing permission has not changed.

Escalation ladder

If the notebook is still missing after the account check, navigation check, sync check, and open command, use a more invasive fix next: sign out of OneNote, close the app, reopen it, and sign back in with the correct account. On Windows, if the issue stays tied to one device, repair or reinstall the app after confirming the notebook exists online.

For service-side issues, check whether OneDrive or SharePoint access is affected before changing anything else. OneNote notebooks are generally stored online, which can allow access on mobile devices and across Windows, Mac, iPad, iPhone, Android, and the web.

Prevention

Keep shared notebooks in OneDrive or SharePoint under the account that actually needs access, and use the same Microsoft account across devices when you want the same notebook list. That reduces account mismatch and makes sync problems easier to spot.

Frequently asked questions

Can't find notebook in onenote

Check the signed-in account first, then check whether the notebook list is hidden. If the notebook exists online, open it through File > Open in OneNote for Microsoft 365. If you still cannot find it, search All Notebooks with an exact phrase in quotation marks.

Why onenote notebooks are missing

They are usually missing from view, not gone. The common causes are a wrong Microsoft account, a hidden navigation pane, an unopened cloud notebook, or a sync problem. OneNote notebooks are stored online in OneDrive or SharePoint, so the same notebook can appear differently by account and device.

Why onenote is not showing all notebooks

If the notebook appears in one version but not the other, compare the signed-in account, then open View Sync Status and run Sync All or Sync Now.

Shared onenote notebook not showing up

Shared notebooks often live in OneDrive or SharePoint, so the first check is whether the invited Microsoft account is signed in. Then open File > Open and look for the shared notebook in cloud storage. If it opens on the web but not in the app, the issue is usually access or app visibility, not deletion.
