Fix ERROR_CSCSHARE_OFFLINE (0X000004EE) Fast

Quick Answer for Advanced Users

Open Sync Center by typing sync center in Start, select Manage offline files, go to the Disk Usage tab, click Change limits, set Temporary files to 0%, then Delete temporary files. Reboot, remap the network drive.

What This Error Actually Means

You're getting 0X000004EE - ERROR_CSCSHARE_OFFLINE when you try to access a network share that was previously marked for offline use. This happens when Windows thinks the share is available offline but can't actually connect to it. The most common scenario: you mapped a drive to a server folder, turned on Always available offline, then either the server moved, the share name changed, or the network path broke. Your local PC still holds a stale cache entry. The error appears in File Explorer, command-line tools, or even in apps trying to read that drive. I've seen this on Windows 10 22H2 and Windows 11 23H2 after a file server migration or a VPN disconnect that left the sync state corrupted.

How to Fix It (Step by Step)

1. Open Sync Center — Press Win + R, type control, hit Enter. In Control Panel, set View to Large icons, then click Sync Center.
2. Manage offline files — In the left pane, click Manage offline files. If you don't see it, you may need to expand the window or search for it via Start.
3. Clear temporary offline files — Go to the Disk Usage tab. Click Change limits. Under Temporary files, slide the bar to 0% (or type 0 in the box). Click OK, then click Delete temporary files. Confirm the prompt.
4. Disable offline files temporarily — On the General tab, click Disable offline files. You'll be prompted to restart. Reboot now.
5. Remap the network share — After reboot, open File Explorer, right-click This PC, choose Map network drive. Pick a drive letter, enter the full UNC path (e.g., \\server\share), check Reconnect at sign-in, and uncheck Connect using different credentials unless needed. Click Finish.
6. Re-enable offline files — Go back to Sync Center > Manage offline files, click Enable offline files, reboot again.
7. Set the share for offline use again — Right-click the remapped drive in File Explorer, choose Always available offline. Wait for the initial sync to complete.

That's the full sequence. Skipping steps 3 and 4 is the #1 reason this fix fails. The temp files hold the broken sync state — you have to purge them.

Alternative Fixes if the Main One Doesn't Work

Delete the Offline Files Cache Manually

If Sync Center refuses to delete temp files, do it manually:

1. Open an elevated Command Prompt (right-click Start > Command Prompt (Admin) or Terminal (Admin)).
2. Type net stop cscsvc and press Enter. This stops the Offline Files service.
3. Delete the cache folder: rd /s /q C:\Windows\CSC. This removes all cached offline files. You'll lose any unsynced changes — so if you have local edits, back them up first.
4. Restart the service: net start cscsvc.
5. Reboot and remap the drive as in steps 5-7 above.

Use Registry to Force Reset

Only if the manual cache delete fails. Open Regedit (Admin), navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Csc\Parameters

Create a new DWORD (32-bit) named FormatDatabase and set its value to 1. Reboot. Windows will rebuild the offline files database from scratch. This wipes all cached offline files — use it as a last resort.

Prevention Tips

To avoid seeing this error again:

• Don't use offline files on shares that move frequently. If your IT team migrates servers or changes paths often, skip the offline setting. Rely on direct network access.
• Unsync before disconnecting. If you know you're leaving the office or disconnecting from VPN, right-click the drive and uncheck Always available offline. Let it sync fully before you go.
• Check the share path regularly. If the server name or folder changes, remove the mapped drive and remap it. Don't just edit the UNC path in the drive properties — that confuses the offline cache.
• Keep Windows updated. Microsoft fixed several offline files bugs in KB5005101 (Windows 10) and KB5030219 (Windows 11). Make sure you're on the latest cumulative update.

That's it. The 0X000004EE error is annoying but it's almost always a cache corruption issue. Clear the cache, remap the drive, and you're back in business.
