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 got a call back from Tier 2 support today and the audio actually worked. The agent was suprised to find out it was a known issue and asked for a link to the PM's answer to this thread saying it was known. I provided that link. I asked for an estimated time of resolution and the agent said they would investigate and respond when they had an answer. As of now (5 hours later), I haven't received a response. I am still currently affected by the issue 48 hours after my first experience. I hope they can get the syncing issue resolved soon, however I am looking at alternatives to OneNote since this experience has soured me on the cloud sync process in general. If anyone has any recommendations for methods to store/sync notes in a similar fashion to a local server that I can host myself they would be much appreciated! My workflow involves syncing between multiple W10 PCs and Android tablets.

They must be having an issue with their phone system too, because the same thing happened to me. I scheduled a call with them for today, they called, and it was completely silent on their end. Emailed them again, they called back, same issue again.
