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!

Hi Mia Zhao. Having one of the most heavily used apps in our Microsoft 365 Apps for Enterprise subscription service is unacceptable. Any luck on a forthcoming resolution?

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
Me as well as I also depend heavily on OneNote for my work and community service work as well.

I am hoping that someone with Microsoft will contact us soon.

FYI - I know my data is there as I just can’t access it on my laptop, my main computer, as I have Microsoft cloud backup.

Hi,

As the general troubleshooting steps all provide no help in this scenario, it needs to be investigated through the remote section and collect logs to fix.

Generally, raise a support ticket and the related team will be able to trace something that affects in your device, investigate it, and fix it. Reference: Get support - Microsoft 365 admin | Microsoft Learn But to create a support ticket, it needs the Microsoft 365 admin privileges, and if you're not an admin for your Office 365 organization, contact the admin for creating a new ticket. Reference: How do I find my Microsoft 365 administrator? - Microsoft Support

If it is currently not available for you to contact the admin to open the ticket, there has the other way to contact online support team for remote session troubleshooting. Click: Contact Us - Microsoft Support

Sincerely,

Mia | Microsoft Community Moderator
