Where is 'lost and found' folder

Question

Where is 'lost and found' folder in onedrive? I keep getting a message at startup saying that 127 files are in 'lost and found' folder.

Answer 1

“Lost and Found” in OneDrive is a folder OneDrive creates when it encounters sync conflicts or files it cannot automatically reconcile with the cloud structure.

This usually happens when:

Files were renamed or moved while offline

Folder structures changed

A sync relationship was reset or repaired

SharePoint/Teams libraries were modified

OneDrive creates a Lost and Found folder to preserve those files rather than deleting them.

You can typically find it in the user’s local OneDrive folder, for example:
C:\Users<username>\OneDrive\
or inside a synced SharePoint/Teams library folder.

It may not appear in the OneDrive web interface — it’s usually created locally by the sync client.

I would recommend checking the local OneDrive folder path on the device where the message appears and reviewing the contents before deleting anything.
