Question details

Files in a shared OneDrive folder temporarily disappear and may return automatically, sometimes displaying 'someone' as the modifier.

How to Investigate Missing or Deleted Files in a Shared OneDrive Folder

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Accessing, syncing, or managing shared files within a OneDrive folder.
Observed behavior: Files mysteriously vanish from the shared folder and sometimes reappear later without user intervention. Modification logs unclearly mark the actor as 'someone'.

Before you start

Before troubleshooting, determine whether your account is OneDrive Personal or OneDrive for Business, and verify that your device has a stable internet connection for accurate synchronization.

Solution 1Recommended

Verify OneDrive Service Health and Sync Status

Server maintenance or temporary synchronization delays often cause files to temporarily disappear and reappear.

Microsoft occasionally experiences server outages or maintenance periods that can interrupt OneDrive file syncing. During these times, shared files might temporarily vanish from your view.

Check Microsoft Service Status

Visit the Microsoft Service Status page (portal.office.com/servicestatus) for Personal accounts, or the Microsoft 365 Admin Center for Business accounts, to look for active OneDrive incidents.

Verify Local Sync Status

Click the OneDrive cloud icon in your system tray or menu bar to ensure it says 'Up to date' and is not stuck processing changes.

Wait for Automatic Resolution

If a service incident is reported, wait 24 hours. In most cases, files and folders return automatically once the server issue is resolved.

Verify OneDrive Service Health and Sync Status

Sync Delay: Files returning automatically within 24 hours is a strong indicator of a temporary server-side issue rather than accidental deletion.

Solution 2

Review Shared Folder Permissions and Recycle Bin

Ensure the folder owner hasn't changed access permissions and check if files were accidentally deleted by another collaborator.

Solution 3

Contact Microsoft Support for Investigation

If files continue to disappear without settings changes, Microsoft Support can investigate backend server logs.

Frequently Asked Questions

Why do deleted files in OneDrive show 'someone' as the user?

This typically occurs when a file is modified or deleted through an automated background server process, during a complex sync conflict, or by a guest user who isn't fully recognized by the sharing link.

Can I recover shared OneDrive files if they do not return automatically?

Yes, you can often recover them by checking the OneDrive Recycle Bin on the web. If they aren't there, ask the folder owner to check their Recycle Bin, or use the 'Restore your OneDrive' feature if you have a Microsoft 365 subscription.

How long does it usually take for files to reappear after a OneDrive server issue?

In most documented service interruptions, files and folders return automatically within 24 hours once the server maintenance or synchronization issue is resolved by Microsoft.

How can I prevent data loss in shared cloud folders?

It is highly recommended to maintain an independent local backup or use an alternative secure storage solution. Copying critical files to a local drive reduces the risk of data loss from sync errors or accidental deletions by collaborators.
