Question details

The user is attempting to resolve synchronization error 0xE00001A1 in OneNote, which prevents a notebook section stored on SharePoint from syncing properly.

Product: Microsoft OneNote, SharePoint
Device & OS: not provided
Scenario: Synchronizing a OneNote notebook hosted on SharePoint using the desktop client.
Observed behavior: Synchronization fails due to unreadable content, triggering error 0xE00001A1. The corrupted page often hides in the online recycle bin and may repeatedly reappear after being deleted.

Before you start

Ensure you have login access to the SharePoint web interface and manually back up any unsynced notes to a local text file before attempting to delete notebook sections.

Solution 1Recommended

Clear Corrupted Pages from the Online Recycle Bin

Use the web version of OneNote and SharePoint to locate and permanently delete the unreadable page causing the synchronization block.

Error 0xE00001A1 is typically caused by unreadable or corrupted content that the desktop client cannot process. Clearing the notebook's online recycle bin directly from the browser often forces the server to clear the sync blockage.

Open notebook in browser

Access the recycle bin

Navigate to the View tab and click on 'Deleted Notes' to access the notebook's online recycle bin.

Delete the corrupted section

Right-click the problematic page or section within the recycle bin and select 'Delete' to remove it permanently, or choose 'Empty Recycle Bin'.

Resync the desktop client

Return to the OneNote desktop application, right-click the notebook name, and select 'Sync This Notebook Now'.

Solution 2

Migrate Content to a New Notebook Section

If the deleted section keeps reappearing from the recycle bin, you must manually isolate the uncorrupted content into a fresh section or notebook.

Frequently Asked Questions

What does OneNote error 0xE00001A1 indicate?

This error code signifies that OneNote has encountered unreadable or corrupted content within a SharePoint notebook, which prevents the application from successfully syncing the section with the server.

Why does a deleted OneNote section keep reappearing after I sync?

The desktop client may be holding a corrupted cached version of the notebook that keeps pushing the broken page back to SharePoint. You must resolve this by deleting the page permanently from the online web version's recycle bin.

Will I lose my notes if I empty the OneNote recycle bin?

Yes, emptying the recycle bin will permanently delete those specific pages. It is highly recommended to manually copy and paste any unsynced text into a local document or a new notebook section before performing the deletion.
