OneNote sync failure error code: 0xE00009C8 bb0ur

Anonymous

Rebooted my PC today to finish Windows updates and now get this on all notebooks: "OneNote can't sync your notes right now. We'll keep trying. (Error code: 0xE00009C8 bb0ur)"

I've closed all notebooks, logged out and back in to my account and can open the notebooks but they all say "There aren't any sections here'.

The following I've done multiple times over the last 56 hours trying to resolve the issue: I've rebooted, performed O365 repair, SFC /SCANNOW, uninstalled/reinstalled O365, ran SARA to completely uninstall O365 the reinstalled, deleted the cache folder in the appdata folder, logged out of OneNote and back in, deleted all entries related to OneNote or my OneDrive account from credential manager. All of which did nothing to resolve the issue. I can open the notebooks on the web app, but when I try to open them in the desktop app from the web app it prompts me to login, I do, then it gives an error message: "We couldnt open that location. It might not exist or you might not have permission to open it." I'm able to create new notebooks from the desktop app tath get saved in my OneDrive, but I can't open any existing OneNote notebooks from my OneDrive.

I have multiple OneNote notebooks with hundreds of pages that I've accumulated of the years so I am not going to recreate (copy/paste) all of the content into new notebooks. Feels like a bad Windows update. Please help!

Hello OneNote community, thank you for your patience as we investigated this syncing issue. We've deployed a fix as of this morning and sync reliability is being restored today (Sept 3rd). To get your notes back in sync, right-click your notebook in the desktop app and select "Sync This Notebook Now." If you're still having issues by the end of the day, please feel free to post in this forum.

We really value all of our incredible users and thank you for sticking with us!

I performed what you suggested and that did not resolve the issue. I then tried OneNote on my Windows 11 laptop. At first my notes appeared, then I did a Windows update and restarted OneNote and all my notebooks have the exact same issue.

I have the same issue and have followed all the steps outlined.

Did the steps Mia Zhao work for you to resolve the issue? For me they didn't help and the OneNote is useless to me now.

Re (Error code: 0xE00009C8 bb0ur)

Same here.

Methods tried to no avail:
- SFC /SCANNOW
- Cleared Appdata cache/backup (%localappdata%\Microsoft\OneNote\16.0)
- uninstalled/reinstalled office 365 multiple times
- app repair (quick and online) for office 365
- cleared all entries in credential managers
- Onenote for Windows 10 (instead of the latest Onenote app that comes with office365)
- readjust time zone setting
- Mia Zhao's methods above: OLicenseClean, clean entries in credential managers again.
Onenote files still usable in web browser, android phone and work laptop running windows 10 (using onenote for windows 10).

Just not syncing with onenote app in personal laptop running windows 11, which is my main device.

(I rely heavily on onenote for work and personal matters)

Still hoping for other suggestions that may work? Thanks
