Question details

The user needs to resolve OneNote sync error 0x2BDF5F, which occurs when notebook sections or attachments have been moved, renamed, or deleted.

Product: Microsoft OneNote
Device & OS: Windows
Scenario: Attempting to synchronize OneNote notebooks after file locations or permissions have changed in OneDrive or SharePoint.
Observed behavior: OneNote fails to synchronize the notebooks and displays the specific error code 0x2BDF5F.

Before you start

Before making any changes, ensure you back up all unsynchronized notes by manually copying and pasting them into a local document, such as Word, to prevent data loss.

Solution 1Recommended

Clear Microsoft Office Credentials and Re-authenticate

Resetting your connection by clearing cached Windows credentials forces OneNote to re-authenticate and establish a fresh synchronization link.

This method clears out outdated or corrupted login tokens that may be preventing OneNote from locating the moved or renamed notebooks in your cloud storage.

Close the notebooks and sign out

Open the desktop app, navigate to File > Info > Settings, and close the affected notebooks. Sign out of all Office accounts and close all Office applications completely.

Access the Windows Credential Manager

Open the Windows Control Panel, navigate to User Accounts, click on Credential Manager, and then select Windows Credentials.

Remove Office credentials

Scroll through the list, locate any credentials related to Microsoft Office, and click 'Remove' for each one.

Restart and reopen from the web

Restart your computer, open the affected notebook in OneNote for the web, click 'Editing', and choose 'Open in desktop app' to force a fresh synchronization.

Clear Microsoft Office Credentials and Re-authenticate

Tip: Opening the notebook from OneNote for the web establishes a direct, updated link to the file's current location.

Solution 2

Restore Missing Notebooks from the Recycle Bin

If the error is caused by accidental deletion, restoring the notebook from your cloud recycle bin will resolve the sync issue.

Frequently Asked Questions

Why did OneNote suddenly stop syncing and show error 0x2BDF5F?

This error typically occurs when a notebook file, a specific section, or an attachment is moved, renamed, or deleted in OneDrive or SharePoint without the OneNote desktop application being properly updated.

Will I lose my unsynced notes if I close the notebook?

Yes, closing a notebook that hasn't successfully synchronized will discard the unsynchronized changes. Always manually copy your unsynced text to another application like Word or Notepad before closing the notebook.

Where can I find the Second-stage recycle bin in SharePoint?

You can find the Second-stage recycle bin link at the very bottom of the standard Recycle Bin page within your SharePoint site collection.

What if clearing the credentials doesn't fix the sync error?

If clearing Windows Credentials doesn't resolve the issue, try creating a brand-new notebook, manually copying the contents of the problematic notebook into the new one, and syncing the new notebook.
