OneNote sync failure error code: 0xE00009C8 bb0ur

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 have the same issue and have been in contact with MS support yesterday (8/30) (case ID# 7050136393), who spun their wheels poking around for two hours remoted into my computer and then told me that it was a known issue and that they'd escalate. Tier 2 called me multiple times today (8/31), each time I picked up the phone I could not hear them, it was as if they were muted. I then received emails saying their calls had been disconnected and needed a new phone number and time to reach me. I have triple checked my phone and have no issues with audio/voice on any other calls. I provided them with that information twice via email response and have not heard back. Given that this is acknowldedged as a known issue, I find their lack of response via email or working phone unsatisfactory, and the lack of urgency in resolving this issue very disappointing. I do not take the security implications of letting a stanger take remote control of my PC lightly, and during their "poking around" they created a new administrator profile on my PC as well as had visibility of my notes (through the web app) and my email, all of which was for nought. This is especially frustrating as I had provided the agent with a link to this thread and impressed upon them that this appeared to server/MS side issue upon the outset of our support chat. I told them that I had multiple devices affected (Android tablet, multiple W10 PCs on varying versions of Office, etc.), and still they insisted on trying multiple things while remotely accessing my main PC. MS, the OneNote team, and the support agents need to do better. I was told that a resolution would be within 24 hours. It has been 24 hours. I realize this is a holiday weekend in the US, but when multiple users are affected and it's effectively a production stop for those users, a resolution needs to be sought with better urgency.

    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.
