Transfer Content to a New Synchronized Notebook

This method isolates the sync error by creating a fresh notebook and moving your unsynced content into it, bypassing the problematic corrupted file.

Often, a specific notebook section or file structure becomes corrupted, preventing communication with the server. Migrating data to a newly created notebook can re-establish a healthy sync connection.

Create a New Notebook

Open OneNote for Mac, go to 'File', and select 'New Notebook'. Give it a recognizable name and wait a moment to ensure it synchronizes successfully with your Microsoft account.

Copy Sections to the New Notebook

Navigate to the old notebook displaying the error. Right-click on a section tab and select 'Copy Section To...'. Choose the newly created notebook as the destination.

Copy Individual Pages (If Sections Fail)

If copying an entire section fails, create a new section in your new notebook. Then, go back to the problematic section, right-click the individual pages, and copy them over one by one.

Contact Microsoft Support

If you are unable to access the notebook entirely or continue to receive a 404 error when trying to open the file online, reach out to Microsoft Support, as the notebook may be missing from the server.

Transfer Content to a New Synchronized Notebook

Avoid Moving Instead of Copying: Always use the 'Copy' function rather than 'Move'. If a sync error interrupts a 'Move' operation, you risk losing the data completely.

Frequently Asked Questions

What does error 0xE0000024 bdf5h mean in OneNote?

This error code typically indicates that OneNote is unable to communicate properly with the cloud server to synchronize your notebook. This is often due to server-side glitches, corrupted sections within the notebook, or authentication issues.

Why do I get a 404 error when opening a OneNote link?

A 404 error means the server cannot find the notebook at the provided link. This happens if the notebook was deleted, moved to a different folder in OneDrive, or if it never successfully synced to the cloud in the first place.

What if I don't have an export or download option in OneNote for Mac?

The Mac version of OneNote often lacks a direct local export button. If you cannot download a backup, your best option is to manually copy your sections and pages into a newly created notebook that is currently syncing properly.
