Frequently Asked Questions

Why do my OneDrive files become corrupted?

File corruption in OneDrive typically occurs due to incomplete syncing, abrupt network disconnections, system crashes while a document is saving, or underlying hard drive issues on the local computer.

Can I use 'Open and Repair' for corrupted PDF files?

No, the 'Open and Repair' feature is specific to Microsoft Office applications like Word and Excel. For PDF files, you should use OneDrive's Version History or rely on a dedicated PDF repair utility.

What should I do if OneDrive Version History has no usable versions?

If all versions are damaged or no previous versions exist, you will need to restore the file from an offline external backup, check the Recycle Bin for older copies, or consult a professional data recovery service.
