OneDrive started to give "we can't sync your onedrive folder" and "We couldn't find your onedrive on SPO"

Question

OneDrive started to give "we can't sync your onedrive folder" and "We couldn't find your onedrive on SPO"

BillP 50

Suddenly after a Windows 11 update on about Oct 27, 2026 I started getting OneDrive failures, including:
"we can't sync your onedrive folder"
"We couldn't find your onedrive on SPO"
I get "Upload Blocked" on files, when OneDrive is working for 30 minutes after a new install
Signing in to Onedrive give a pop up box with a spinning circle

I have a Family M365 account with lots of OneDrive storage available.
PC is running Windows 11 Pro.

I tried lots of things to fix OneDrive but none worked:

onedrive.exe /reset
"Also, unlink and relink your OneDrive account. Open OneDrive Settings, go to the Account tab, and click Unlink this PC. Then, sign in again and set up OneDrive from scratch."
Also deleted Windows credentials for OneDrive
Also uninstalled then reinstalled OneDrive - then it works for 30 minutes and then "couldn't find your onedrive on SPO" always appears
Also did a Windows refresh in place when app are retained.
Also did a pause then resume on OneDrive (when I get it working after a new install of OneDrive)
Signed out of M365 apps, then signed back in.

I only have one account for M365 and the same account is used by OneDrive

I don't use Sharepoint

Windows is up to date - but this is seemed to have caused the problem since I have other PCs and once they get the update and then restart, OneDrive fails.

Thanks

Be sure the Settings / About / Insider program button is checked.

I have multiple PCs, but only have this issue on the one with OneDrive folders being in the root folder of C:, e.g. C:\OneDrive.
Other PCs where OneDrive is in a subfolder, or on other drive (e.g. E:\OneDrive) doesn't have this issue.
When I moved the C:\OneDrive, to a subfolder the problem solved.

Hi Viktor,

I checked other language Q&A with same issue and interestingly, we found one thing in common which is we both put OneDrive under C:\ directly.

It seems Microsoft is now making more strict folder rules directly under C:.

When I followed the solution showed here (re-install and update the insider version), the installation stuck right after folder setting. I have to change folder setting to C:\user\public to move on with installation.

I am not sure if all people with this issue has same OneDrive root configuration, but if there is anyone rooting under C:\ directly, it is strongly advised to change the root before further issues may occur with new versions.

I was having the same problem, I also had my OneDrive folder directly in the C:\ drive. All i did to fix it was move it in to my C:\Users-username-\ folder and it started working again.

Hello again,

Updating to 26.198.1011.0006 INSIDER version solved the problem.

This method saved me for now:

Clean uninstall OneDrive
Delete the folder and all the files from your computer
I don't know is it necessary but I also deleted all the program and setting folders associated with Onedrive
Restart PC
Download the last version of Onedrive and install
Login your account and wait for the first sync process (I didn't download any of my files, just used selective download)
After sync completed, go to SETTINGS > ABOUT page and turn on the Insider version download, close settings and wait for OneDrive to update itself to the Insider version. After update OneDrive will restart. Check if it's version is 26.198.1011.0006
Restart PC and check the problem solved or not.

Like I said, these steps worked well for me, I hope it proves useful to you as well.

Thanks, the 26.198.1011.0006 INSIDER version of OneDrive has been working with no problems .
Here's what I did:

Kill any OneDrive process (version 26.195.1006.0007)

Disable automatic Windows updates

Uninstall OneDrive

Restart the PC

I had to download an older version of OneDrive, version 26.183.0920.0005
You can get this from https://skydrive.en.uptodown.com/windows/download

Install that old version, just double click the .exe

You must now act very quickly to sign in to OneDrive and then click on the Insider version.
If you are too slow OneDrive might try to automatically update itself - then you need to start over.

The Insider version is now working, but you need to keep Automatic Updates off.

I did not need to delete the contents of my local OneDrive folder.

I too experienced this problem on my desktop and 2 laptops starting on October 30. First the odd error message “We couldn’t find your Onedrive on SPO folder in c:\onedrive.” Any subsequent attempts to get into Onedrive asked for me to sign back in, but attempts to do so resulted in a never-ending twirly loop. I tried all of the other proposed fixes of the last couple of days and none worked, until I found this thread and the solution provided by Tugrul and BillP. I needed an old version to get past the sign in issue, and once I got in I set the Insider edition switch and was shortly updated to Insider 26.198.1011.0006. So far so good.

One thing I did not do is disable Windows Updates. My understanding (per ChatGPT) is that Onedrive has a separate update mechanism from Windows Updates, so turning it off shouldn’t make a difference. (And I noted that there were no Onedrive updates listed in the Windows Update History.)

Thanks again for the help!

Pavel, I’m glad you were able to fix it without deleting the files on your computer; I tried the same thing you did (selecting the previous folder) multiple times, but it just wouldn’t work for me, so I ended up having to delete them.

Confirming this fix on 2 more PCs (personal account, Win 11 Pro 26H2, build 26300.9711, sync folder C:\OneDrive).

Laptop (stuck on the spinning sign-in):

Uninstalled OneDrive and restarted (did not delete my files; renamed the old local folder as a backup).

Installed the official older build 26.189.0928.0009 using the "Released / amd64" link in the Production row of Microsoft's OneDrive Sync Release Notes page (no third-party download needed). It signed in normally.

Immediately enabled Insider in Settings > About -> updated to 26.198.1011.0006. Restarts fine since then.

Office PC (was working on 26.195 after moving the sync folder to a different path):

Enabled Insider in Settings > About -> it updated to an even newer build, 26.204.1019.0004. Then moved the folder back to C:\OneDrive (unlink, move folder, relink with "Use this folder"). Working fine.

I did not disable Windows Update.

Hello BillP,

Thank you for listing everything you have already tried.

Since the issue returns shortly after reinstalling OneDrive and also affects the sign-in window, this may involve cached OneDrive sign-in configuration rather than storage capacity or an individual file.

Before proceeding, please sign in to OneDrive on the web and confirm that your important files are available there. Also copy any files showing Upload Blocked that exist only on the PC to a separate folder outside OneDrive.

Then try the following:

Completely close OneDrive and all Microsoft 365 applications.
Press Windows key + R.
Enter: %localappdata%\Microsoft\OneDrive\settings
Find and delete PreSignInSettingsConfig.json.
Restart Windows, open OneDrive, and sign in again with your personal Microsoft account.

If the sign-in window continues spinning, temporarily connect one affected PC through a mobile hotspot and test OneDrive again. This can help determine whether the sign-in request is being interrupted by the normal network, DNS configuration, security software, or firewall.

Please also provide the following so the issue can be narrowed down:

The Windows version and OS build shown under Settings > System > About
The OneDrive version under OneDrive Settings > About
The Windows update KB number installed immediately before the issue started
Whether OneDrive on the web opens normally
Whether the problem remains when using a mobile hotspot

Because the same behavior appears on multiple PCs after restarting, please avoid deleting the OneDrive folder or repeatedly reinstalling it until the cloud copy and any unsynced local files are secured.

Please feel free reply back to this post if you need further assistance, I'll be happy to help.

Thanks for the prompt response.

I tried the two suggestions on 2 PCs and still I get the same failure after signing in and selecting the OneDrive folder: a white popup box with a spinning circle, with "Microsoft OneDrive" text at the top left, and nothing else. The spinner does not stop.

Here's information about my PCs:

Windows version and OS build shown under Settings > System > About
Windows 11 Pro 26H2 10/‎29/‎2026 OS Build 26300.9818

The OneDrive version under OneDrive Settings > About
OneDrive device ID: ee0a8566-e273-efbf-c1e5-58a669369c7a
OneDrive version: Build 26.195.1006.0007 (64-bit)

The Windows update KB number installed immediately before the issue started: Note these KBs were installed on 10/25/2026, a few days before the Onedrive problems:
KB5133966
KB5133964

And I also see these versions of OneDrive were released on 10/23/2026, the release notes list lots of features so maybe something was broken here:
26.195.1006.0007
26.189.0928.0009

Whether OneDrive on the web opens normally
OneDrive.com in the web works OK

Whether the problem remains when using a mobile hotspot:
OneDrive still fails when connected through a mobile hotspot, and I tried 2 PCs.

And the OneDrive app works OK on my Android Pixel 7 phone.

Same issue on 2 of my PCs (personal Microsoft account, sync folder C:\OneDrive).

Comparison that may help narrow it down:

PC1 (office): Win 11 Pro 26H2, build 26300.9711. OneDrive 26.195.1006.0007 installed 28/10 19:18 - error appeared the same day (28/10). Has KB5133964 + KB5133966.

PC2 (laptop): Win 11 Pro 26H2, build 26300.9711. OneDrive 26.195.1006.0007 installed 31/10 14:56 - error appeared 1/11. Has KB5133964, does NOT have KB5133966.

KB5133964/KB5133966 are .NET 8/10 updates, not Windows cumulative updates, and my Windows build differs from yours (9711 vs 9818).

The only common factor across all three PCs is OneDrive build 26.195.1006.0007. On both my PCs the error appeared within a day of that build being installed.

The local folder exists and is intact; OneDrive on the web works normally.
