How to Fix OneDrive Error 0x80070185

OneDrive error 0x80070185 usually appears with the message “The cloud operation was unsuccessful.” You may see it when opening, downloading, copying, moving, or deleting a OneDrive file in Windows, especially when the file is online-only or its sync status is stuck.

The error can look like a file corruption problem, but I would not assume the file itself is damaged. OneDrive Files On-Demand allows File Explorer to display cloud files that are not fully stored on the PC. When Windows asks OneDrive to retrieve or manipulate one of those files and the cloud operation fails, 0x80070185 can appear.

The safest troubleshooting path is to first confirm that the affected file still works on OneDrive on the web. After that, determine whether the problem affects one file, one synchronized library, or the entire OneDrive client. That distinction tells you whether to focus on the file, local sync state, network, account connection, or Microsoft 365 environment.

What Does Error 0x80070185 Mean?

Error 0x80070185 is associated with the message:

The cloud operation was unsuccessful.

Microsoft specifically references this OneDrive error code in its support material and recommends making sure the computer and OneDrive versions are up to date.

The error can occur because Windows File Explorer and OneDrive are working with two different file states.

A OneDrive file may be:

• Online-only
• Downloading
• Locally available
• Marked to always remain on the device
• Waiting to sync
• Stuck in a pending sync state
• Located in a shared or SharePoint-backed library

An online-only file can appear in File Explorer without its complete contents being stored locally. When you open or copy it, OneDrive must retrieve the actual file from the cloud.

If that operation cannot be completed, Windows may return 0x80070185.

Common Symptoms of OneDrive Error 0x80070185

The exact symptom matters because not every 0x80070185 case has the same cause.

You may encounter the error when:

• Opening a OneDrive file from File Explorer
• Selecting Always keep on this device
• Copying a OneDrive file to a local folder
• Copying cloud files to an external drive
• Moving a file out of OneDrive
• Deleting a file whose status is stuck on Sync pending
• Downloading a large group of files
• Accessing a synchronized SharePoint or work library
• Using an old or unsupported OneDrive/Windows configuration

Microsoft community reports show the code appearing while users try to download files, make files locally available, copy or move OneDrive data, and delete items whose availability status remains stuck.

That is why a useful guide needs to diagnose the failed cloud operation rather than treat 0x80070185 as a generic Windows error.

Check the File on OneDrive.com First

Before resetting anything, check whether the cloud copy is healthy.

Open OneDrive in a browser and sign in with the same Microsoft account used on the affected computer.

Find one of the files that generates error 0x80070185.

Try to:

1. Open the file through the web interface.
2. Download it through the browser.
3. Check whether its expected name and size are present.
4. Try another file in the same folder.

If the file works online

That strongly suggests the cloud copy is accessible.

The problem is more likely somewhere between File Explorer and the local OneDrive sync client.

You can then concentrate on:

• Files On-Demand
• Local synchronization
• Network stability
• Free disk space
• OneDrive reset
• Account relinking

For important data, downloading a browser copy before deeper troubleshooting also gives you an additional local copy.

If the file fails online too

Do not spend all your time repairing Windows.

Check:

• Whether you are using the correct account
• Whether the file was moved or deleted
• Whether a shared file is still shared with you
• Whether your work or school permissions changed
• Whether the OneDrive account has a broader problem

For managed Microsoft 365 accounts, your administrator may need to investigate the library, account, or service.

Determine Whether One File or Many Files Are Affected

Test several files before applying broad repairs.

Try:

• The original problem file
• A small file in the same folder
• A file in another OneDrive folder
• A newly created test file
• A locally available OneDrive file
• An online-only OneDrive file

If only one file produces 0x80070185, focus on that file or folder.

If many unrelated online-only files fail, OneDrive’s local cloud-file operation is a stronger suspect.

If your personal OneDrive works but a synchronized work or SharePoint library fails, investigate that library and its permissions rather than resetting Windows.

Look at the OneDrive File Status

File Explorer’s OneDrive status icons provide useful clues.

An item may be online-only, locally available, always available locally, syncing, or waiting to sync.

If the affected file says Sync pending, give OneDrive a chance to finish processing changes before forcing another operation.

Select the OneDrive cloud icon in the notification area and look for:

• Processing changes
• Sync paused
• Sign in required
• Storage full
• OneDrive isn’t connected
• A specific file sync error

Resolve an obvious warning first.

For example, if OneDrive has lost its account session and asks you to sign in, resetting Windows components would not address the actual problem.

Restart OneDrive

A temporary OneDrive process failure is easy to test.

Select the OneDrive cloud icon in the notification area, open its settings menu, and quit OneDrive.

Then:

1. Open Start.
2. Search for OneDrive.
3. Launch the desktop app.
4. Wait for it to sign in.
5. Let any immediate synchronization finish.
6. Retry the affected file.

Restart Windows as well if OneDrive does not restart cleanly.

If the error disappears, there is no reason to proceed to more disruptive repairs.

Pause and Resume Syncing

A stalled synchronization queue can sometimes recover after pausing and resuming OneDrive.

Open the OneDrive cloud menu, pause synchronization briefly, and then resume it.

Wait until OneDrive has processed its current changes.

Test one affected file afterward.

This step is particularly useful when 0x80070185 appeared during a large download or after the PC resumed from sleep.

If the same error immediately returns, continue with the diagnostic steps below rather than repeatedly toggling sync.

Check the Internet Connection

Online-only files need a stable connection before OneDrive can hydrate them.

Test the network with more than a lightweight webpage. Download a normal file through your browser or stream something briefly.

If the connection is unstable:

• Reconnect Wi-Fi
• Restart the router if other devices are affected
• Try Ethernet if available
• Temporarily disconnect a VPN
• Try a different network
• Avoid a large cloud download over a weak hotspot

If OneDrive works normally on another network, investigate the original network, VPN, proxy, firewall, or organization policy.

A file can remain visible as a cloud placeholder even while the connection required to retrieve it is failing.

Make One Problem File Available Locally

If 0x80070185 appears while opening or copying an online-only file, test the download itself.

Right-click one small affected file and choose Always keep on this device when available.

Wait for OneDrive to download it.

Then try opening it.

If it becomes locally available and opens successfully, the problem may have been transient or tied to the previous cloud hydration attempt.

If selecting Always keep on this device itself produces 0x80070185, you have stronger evidence that the failure is occurring while OneDrive tries to retrieve the cloud content.

That makes network, sync-client, account, Files On-Demand, and service-side checks more relevant.

Check Free Disk Space

OneDrive cannot make an online-only file local without storage space.

Open:

Settings > System > Storage

Check the free space on the drive that contains your OneDrive folder.

This becomes especially important when OneDrive appears stuck downloading several gigabytes or when you choose to make a large folder available offline.

Do not judge required space solely from what File Explorer currently reports for online-only placeholders. Once the files are downloaded, their real contents consume local storage.

Free enough space for the download plus normal Windows operations and try again.

Download a Small Batch Instead of the Entire Folder

Large cloud operations make diagnosis difficult.

If 0x80070185 occurs while downloading or copying hundreds of files, stop testing the entire folder.

Choose one small folder or several files and make those available locally first.

If the small group succeeds, increase the batch gradually.

This can expose:

• A single problematic file
• A stalled placeholder
• A storage limit
• An unstable network
• A specific shared folder problem
• A path or filename issue
• A transfer that is simply too large to diagnose as one operation

For important data migrations, smaller verified batches are also safer.

Update Windows and OneDrive

This step deserves more attention for 0x80070185 than it gets in many old troubleshooting guides.

Microsoft’s support documentation specifically says that if you see Error 0x80070185: “The cloud operation was unsuccessful,” you should check that the computer and OneDrive versions are up to date.

Install available Windows updates and restart the computer.

Then make sure OneDrive is current.

This is especially important if the machine is running an old Windows release or has not received OneDrive updates for a long time.

Microsoft ended OneDrive desktop synchronization support for Windows 7, Windows 8, and Windows 8.1. On unsupported systems, the correct long-term fix is not to keep applying modern Windows 11 troubleshooting steps to an obsolete sync environment.

Reset OneDrive

If the files work on OneDrive.com but 0x80070185 continues across multiple local files, reset the OneDrive client.

Microsoft states that resetting OneDrive can resolve synchronization problems and that you will not lose files or data by resetting it.

The reset disconnects sync connections and makes OneDrive perform a full synchronization afterward.

Microsoft’s current Windows support instructions use the OneDrive reset workflow and currently document wsreset.exe as part of the procedure for applicable installations.

Press Windows + R, enter:

wsreset.exe

and select OK.

A blank Command Prompt window may briefly appear and close, and Microsoft Store may open. Microsoft says these can be ignored.

Then manually restart OneDrive:

1. Open Start.
2. Search for OneDrive.
3. Launch the OneDrive desktop app.
4. Allow synchronization to rebuild.
5. Test the affected file again.

Some OneDrive installations and older support procedures use different reset methods. If your installation does not match the current Microsoft procedure, use the reset instructions Microsoft provides for your installed OneDrive app rather than deleting random application-data folders.

What a OneDrive Reset Changes

Resetting OneDrive is broader than simply restarting it.

Microsoft says the process resets OneDrive settings and disconnects sync connections. OneDrive then rebuilds its local state and performs a full sync.

Your cloud files are not deleted by the reset.

However, always distinguish between files already stored in OneDrive and files that exist only locally because they never finished syncing.

Before any major sync repair, check OneDrive’s status and back up irreplaceable local-only work.

If you had previously selected only certain folders to sync, Microsoft notes that you may need to choose those folders again after the reset.

Unlink and Relink the PC

If the reset does not fix 0x80070185, rebuild the connection between the computer and the OneDrive account.

Microsoft says unlinking and relinking can resolve sync problems and does not cause data loss. The local folders are temporarily disconnected from the cloud.

To unlink OneDrive:

1. Select the OneDrive cloud icon.
2. Open Help & Settings > Settings.
3. Go to the Account tab.
4. Select Unlink this PC.
5. Confirm Unlink account.

Sign in again afterward.

When OneDrive says a folder already exists, make sure you select the intended existing OneDrive folder.

OneDrive may initially restore cloud placeholders rather than download every file to the PC. That is normal Files On-Demand behavior.

Wait for the client to settle before testing the affected file.

Clear the OneDrive Pre-Sign-In Configuration if Relinking Is Stuck

Microsoft’s current relinking guidance includes a targeted Windows procedure for clearing sign-in credentials/configuration.

Press Windows + R and enter:

%localappdata%\Microsoft\OneDrive\settings

Select OK.

Microsoft identifies PreSignInSettingsConfig.json as the file to remove in this specific procedure.

Then open OneDrive and sign in again.

This is much more precise than deleting everything inside OneDrive’s local application-data folders.

I would only remove files Microsoft specifically identifies for the repair you are performing.

What if Error 0x80070185 Appears When Deleting a File?

Some users encounter the error while trying to delete a OneDrive file whose availability state says Sync pending.

Check whether the file exists on OneDrive.com.

If the web interface can manage the file normally but File Explorer cannot, the local synchronization state is the likely place to focus.

Let OneDrive finish current sync work, restart it, and reset or relink the client if the stuck state affects multiple items.

Be careful about deleting files from the web as a troubleshooting experiment. A normal OneDrive deletion can synchronize to other devices and may remove the file from both the cloud and synchronized computers.

If the file matters, keep a verified copy before deleting it anywhere.

What if 0x80070185 Appears While Copying Files?

Copying an online-only OneDrive file requires the actual data to be downloaded before Windows can complete the copy.

This becomes particularly visible when copying cloud files to:

• A normal local folder
• An external SSD
• A USB flash drive
• An SD card
• Another backup location

I recommend making a small group of files locally available first.

Confirm that they open correctly.

Then copy them to the destination and verify the copies.

For a large migration, repeat the process in manageable batches.

This separates the cloud download from the destination copy and makes it much easier to identify which stage is failing.

Check External Drive Requirements

If your actual OneDrive folder is located on an external drive, pay close attention to Microsoft’s storage requirements.

Microsoft documents cases where OneDrive cannot synchronize to an SD card or external USB drive unless the storage uses a supported configuration, including NTFS for the documented Windows procedure.

Do not format an external drive merely to test a theory.

Formatting erases the drive.

If your OneDrive folder is on external storage and the configuration does not meet Microsoft’s requirements, first back up everything on that drive. Only then consider changing its file system using Microsoft’s documented procedure.

If you are merely copying OneDrive files to an external backup drive, that is different from hosting the active OneDrive sync folder on that drive.

If You Recently Moved the OneDrive Folder

Moving the OneDrive root folder incorrectly can create confusing synchronization behavior.

Microsoft’s supported procedure for changing the OneDrive folder location is:

1. Unlink OneDrive.
2. Move the OneDrive folder.
3. Relink OneDrive to the new location.

If 0x80070185 started after manually dragging the active OneDrive folder to another drive, rebuild the configuration using the supported procedure.

Do not repeatedly move the live folder while OneDrive is actively syncing.

Check Work, School, and SharePoint Libraries Separately

OneDrive for work or school can synchronize Microsoft 365 and SharePoint libraries.

If your personal OneDrive files work but a work library produces 0x80070185:

1. Open the affected library in a browser.
2. Confirm your account still has access.
3. Test a different file in the same library.
4. Ask whether coworkers have the same problem.
5. Check whether the library or folder was moved.
6. Contact the Microsoft 365 administrator if the issue is organization-specific.

A Microsoft community report about 0x80070185 described files working through the web while the locally synchronized department library failed intermittently. That kind of symptom should push the investigation toward the sync relationship or environment rather than the files themselves.

Check Microsoft Service Health

A cloud operation depends on the cloud service.

If OneDrive.com is also slow or failing, multiple users are affected, or the problem suddenly appears across several PCs, check Microsoft’s current service status.

For a work or school account, Microsoft 365 administrators can inspect service health from the organization’s admin tools.

Do not repeatedly reset several computers if the actual problem is upstream.

Reinstall OneDrive Only After the Sync Repairs Fail

Reinstalling OneDrive is reasonable when the local app itself appears damaged, but it should not be your first response.

Before reinstalling, I would have already:

• Verified the files on OneDrive.com
• Restarted OneDrive
• Checked the network
• Checked disk space
• Updated Windows and OneDrive
• Reset OneDrive
• Unlinked and relinked the account

If the client still behaves incorrectly, uninstall OneDrive through Windows Settings where supported, restart the computer, and install the current OneDrive client from Microsoft.

The files stored in your OneDrive account remain in the cloud when the local app is removed.

Again, check for unsynced local-only files before uninstalling any synchronization application.

Avoid Random Cache Deletion

Some old forum solutions for OneDrive errors recommend deleting vaguely described “cache” folders.

That can be risky because OneDrive keeps synchronization and application state under its local data directories.

Use Microsoft’s supported reset procedure instead.

If Microsoft identifies a specific configuration file such as PreSignInSettingsConfig.json for a particular repair, follow that targeted instruction rather than wiping an entire directory.

Avoid Registry Changes Unless They Match a Documented Cause

There is no good reason to begin 0x80070185 troubleshooting by changing unrelated Registry values.

The error tells you that a cloud operation failed.

Start with evidence directly related to that operation:

• Does the file work online?
• Can OneDrive download it?
• Is synchronization stuck?
• Is the PC online?
• Is there enough disk space?
• Are Windows and OneDrive current?
• Does resetting the sync client help?

Registry editing should be reserved for a specific, documented configuration problem, not used as a generic cure for every Windows error code.

Error 0x80070185 vs Error 0x80070184

These two codes can appear in similar OneDrive and cloud-file situations, but they are not interchangeable.

0x80070185 commonly appears with “The cloud operation was unsuccessful.”

0x80070184 is another cloud sync provider error that can occur when Windows cannot complete an operation involving cloud-backed files.

The troubleshooting overlap is real because both can involve Files On-Demand, synchronization, connectivity, and local OneDrive state.

However, the exact error should determine which guide you follow.

If your PC shows 0x80070184, use the TechWise Zone guide to fix OneDrive error 0x80070184.

Error 0x80070185 vs Error 0x80070194

Error 0x80070194 is commonly associated with the message “The cloud file provider exited unexpectedly.”

That points more directly toward the local cloud-file provider unexpectedly stopping while Windows is trying to use it.

Error 0x80070185 instead reports that the cloud operation itself was unsuccessful.

Both can prevent OneDrive files from opening, downloading, copying, or moving, and both may ultimately require a OneDrive reset or relink.

But they deserve separate diagnostic pages because users are searching for a specific code and the symptoms are not identical.

If you see 0x80070194, follow the dedicated TechWise Zone guide to fix OneDrive error 0x80070194.

Which OneDrive Error Guide Should You Use?

Use the exact code displayed by Windows:

• 0x80070184: cloud sync/provider operation problem
• 0x80070185: “The cloud operation was unsuccessful”
• 0x80070194: “The cloud file provider exited unexpectedly”

The three errors belong to the same broader OneDrive cloud-file troubleshooting family, which is why some fixes overlap.

The important thing is not to duplicate every step blindly. The symptom that accompanies the code should guide the order in which you troubleshoot.

The Troubleshooting Order I Recommend

For most Windows PCs showing OneDrive error 0x80070185, I would use this sequence:

1. Check the affected file on OneDrive.com.
2. Determine whether one file or many files fail.
3. Inspect the OneDrive sync and availability status.
4. Restart OneDrive.
5. Pause and resume synchronization.
6. Check the network connection.
7. Try making one affected file locally available.
8. Check free disk space.
9. Test a small batch instead of a huge folder.
10. Update Windows and OneDrive.
11. Reset OneDrive.
12. Unlink and relink the PC.
13. Use Microsoft’s targeted sign-in configuration cleanup if relinking is stuck.
14. Investigate external storage or a moved OneDrive folder when relevant.
15. Check work/SharePoint permissions and Microsoft service health.
16. Reinstall OneDrive only after the earlier repairs fail.

This sequence begins with diagnosis and reversible changes. Broader repairs come later.

Frequently Asked Questions

What is error 0x80070185?

It is a OneDrive/cloud-file error commonly displayed as “The cloud operation was unsuccessful.” It can occur while Windows tries to open, download, copy, move, or delete a cloud-backed file.

Does error 0x80070185 mean my files are corrupted?

Not necessarily. Open OneDrive in a browser and test the affected file. If it opens or downloads normally there, the cloud copy is accessible and the local sync path is a stronger suspect.

Why does 0x80070185 happen when I choose Always keep on this device?

That command tells OneDrive to download an online-only file. If the cloud download or local sync operation fails, Windows may return 0x80070185.

Can low disk space cause problems with OneDrive cloud files?

Yes. An online-only file consumes little local space until OneDrive downloads it. Making many files available locally requires enough free disk capacity for their actual contents.

Should I update OneDrive?

Yes. Microsoft specifically advises checking that both the computer and OneDrive are up to date when error 0x80070185 appears.

Is resetting OneDrive safe?

Microsoft says you will not lose files or data by resetting OneDrive on Windows. The reset rebuilds OneDrive’s local settings and synchronization connections.

Will unlinking OneDrive delete my cloud files?

No. Microsoft says unlinking and relinking does not cause data loss. Local folders are temporarily disconnected from the cloud and reconnect after you sign in again.

Why can I access the file online but not in File Explorer?

That usually indicates the cloud copy is accessible but something in the local OneDrive, Files On-Demand, network, storage, or Windows cloud-file path is failing.

Can 0x80070185 affect SharePoint files?

Yes. OneDrive can synchronize SharePoint and Microsoft 365 libraries, and cloud-operation failures can occur in those synchronized locations too.

Is error 0x80070185 the same as 0x80070194?

No. They can produce overlapping OneDrive symptoms, but 0x80070194 is associated with the cloud-file provider exiting unexpectedly, while 0x80070185 reports that the cloud operation was unsuccessful.

Diagnose the Failed Cloud Operation Before Making Major Changes

The best clue in error 0x80070185 is the message itself: the cloud operation was unsuccessful.

Start by checking whether the file works on OneDrive.com. If it does, focus on the local path that Windows uses to retrieve and synchronize that file. Check its availability status, network connection, disk space, and OneDrive client before escalating to a reset or account relink.

If the same file fails through the web interface, move the investigation toward the cloud copy, account, permissions, shared library, or Microsoft service instead.

That distinction keeps the troubleshooting focused and reduces the chance of making unnecessary Windows changes while trying to repair what is fundamentally a OneDrive synchronization problem.
