Question

OneNote won't sync and error code doesn't match any on the Help page.

Tahlia 0

One of my notebooks won't sync on the desktop app but syncs on my tablet and on the web page. It's been doing this since the 23rd of March. I have already closed and reopened the notebook, I hate deleted and reinstalled the app, and followed the directions shown on the Help page. It has been showing me "OneNote can't sync your notes right now. We'll keep trying. (Error code: 0xE000170D 4oxye | [Moderator note: personal info removed])" and "OneNote can't sync your notes right now. We'll keep trying. (Error code: 0xE0000057 bhhdz)". It's getting on my nerves and I can't figure out how to fix it. Any advice?

Suggest you go to Copilot and type in the text you've written above. I did that & got:

Those two OneNote errors — 0xE000170D and 0xE0000057 — usually mean OneNote is stuck on a corrupted cache, a conflicted notebook section, or a credentials glitch. They’re annoying, but they are fixable. Let’s walk through this in a clean, structured way that fits how you like to troubleshoot: step‑by‑step, device‑specific, and with the “why” behind each action.

Hi @Tahlia,

Good day, and I appreciate the detailed description of your issue.

I understand how frustrating it is when a notebook syncs fine on OneNote for the web and tablet but won’t sync in the Windows desktop app. In most cases, that pattern points to a local desktop-client connection or cache issue, or a specific section blocking upload.

To help narrow this down, could you clarify a few details?

Is this notebook stored in OneDrive or a SharePoint or Teams site?
In OneNote desktop, does View Sync Status show one specific section failing, or the whole notebook?
Are you signed into more than one account (school or work + personal) in OneNote on the PC?
Do you see your latest edits in OneNote for the web?
Are you using OneNote (Microsoft 365) or OneNote 2016 on Windows?

While we investigate, you can try these steps to force a fresh connection:

Force a desktop re-sync: In OneNote desktop, go to File > Info, copy the notebook URL, and paste it into your browser. Once it opens, click Open in desktop app to refresh the link.
Check sync status: Go to File > Info > View Sync Status, click Sync All, and note if a specific page or section is named in the error.
Handle stuck sections: If one section is stuck (common with 0xE0000057), create a new section, move the pages into it, and try syncing again. Also, empty the Notebook Recycle Bin.
Update OneNote: Go to File > Account > Update Options to ensure you are on the latest build.

Important: please do not to rely on sign-out or reinstall as a primary sync fix because it can risk losing any unsynced local changes. Only do that after confirming everything is safely visible online.

The error code 0xE000170D 4oxye generally points to a SharePoint configuration or security policy issue, such as sensitivity labels or Microsoft Information Protection (MIP) restrictions. Since these settings are managed at the organizational level, please contact your IT department. They can investigate the root cause and, if necessary, escalate the issue by opening a support ticket through the Microsoft 365 Admin Center.

Please let me know if these steps help resolve the connection or if you identify a specific section causing the block. I am happy to continue troubleshooting this with you once you have those details from the sync status.
