OneDrive files missing, cloud-only, or won’t open offline

OneDrive files vanished from File Explorer, show cloud icons, or will not open offline? Files On-Demand, Recycle Bin, Known Folder Move and admin checks.

"All my files have gone." It is the most stressful sentence in an MSP queue, and with OneDrive it is usually not true. Files On-Demand shows files that live in the cloud without downloading them, so a file can look present but fail to open offline, look absent because the sync client stopped, or genuinely move to the Recycle Bin because a colleague tidied a shared folder. Calm the user down, then check where the files actually are.

Step one: check the browser

Sign in to office.com and open OneDrive, or the SharePoint site for team libraries. If the files are there, the data is safe and you are fixing the PC. If they are not, go to the Recycle Bin section below before doing anything else. Only consult the SharePoint and OneDrive status page if browser access fails for many users.

Understand the icons

• Blue cloud — online-only. The file exists, uses no disk space, and needs internet to open.
• Green tick outline — locally available because you opened it. Windows may free up space later.
• Solid green tick — always keep on this device. Available offline.
• Red cross or sync arrows that never stop — a sync problem. See OneDrive not syncing.

A user going on a train or flight should right-click the folders they need → Always keep on this device before leaving.

Files show but will not open

1. Is OneDrive running? Look for the cloud icon in the system tray. If it is missing, start OneDrive from the Start menu. Online-only files cannot download if the client is not running.
2. Is it signed in? Click the tray icon. A banner asking to sign in means the token expired — often after a password change or a Conditional Access update.
3. Error "The cloud file provider is not running". Restart OneDrive. If that fails, reset it: run %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, wait, then start OneDrive again. A reset re-syncs but does not delete cloud files.
4. Offline. Online-only files need a connection. Connect, or use the browser.
5. Disk full. Opening a large online-only file needs local space. Free space or open it in the browser.

Files are really missing

1. OneDrive Recycle Bin. In the browser, open OneDrive → Recycle bin. Deleted items stay for a retention period (Microsoft documents 93 days for work and school accounts, across the first- and second-stage bins). Restore from there.
2. Second-stage Recycle Bin. Site collection admins can see items deleted from the first-stage bin. Check before declaring data lost.
3. Shared folder deletions. If someone deleted a shared folder they owned, it is in their Recycle Bin, not the user's. Ask the owner, or the admin, to restore it.
4. Moved, not deleted. Search in the browser. A file dragged into the wrong subfolder looks deleted.
5. Restore your OneDrive. For mass deletion or ransomware, Settings → Restore your OneDrive rolls the whole library back to a point in the last 30 days.
6. Version history. If a file exists but the content is wrong, right-click → Version history in the browser.

Desktop and Documents look empty

Known Folder Move redirects Desktop, Documents and Pictures into OneDrive. If KFM was enabled or a new profile was created, files may now be under C:\Users\name\OneDrive - Company\Desktop rather than the old local path. Check both locations before panicking. If someone unlinked the PC, the old local copy may remain in the user profile while the OneDrive folder shows only online files.

Admin checks

• Storage Sense policies can turn locally available files back to online-only after a period. Users then find files unavailable offline. Adjust the policy if needed.
• Intune OneDrive settings (silent sign-in, KFM, Files On-Demand) — confirm the device received them.
• Retention policies in Microsoft Purview may preserve copies of deleted content even after the Recycle Bin is empty. Check before telling anyone data is gone.
• Audit log. Purview audit shows who deleted or moved files and when — useful when a shared folder disappears.

When to escalate

Escalate to Microsoft when browser access fails across the tenant and Service health names OneDrive or SharePoint. Escalate internally to security if a mass deletion or encryption event is suspected. Most "missing files" tickets close at the Recycle Bin or the cloud icon.

FAQ

Where did my OneDrive files go?

Check OneDrive in a browser first. Files may be online-only, moved to another folder, or in the Recycle Bin. Deleted work files stay in the Recycle Bin for a retention period.

Why can I not open OneDrive files offline?

Online-only files need an internet connection and a running, signed-in OneDrive client. Right-click folders and choose Always keep on this device before going offline.

Does resetting OneDrive delete my files?

No. Resetting the client re-syncs from the cloud. It does not delete files stored in OneDrive. Confirm files are visible in the browser before resetting.

Can I restore a whole OneDrive?

Yes. In OneDrive on the web, Settings then Restore your OneDrive rolls your files back to a point in the last 30 days.
