Hi @CC
I’m sorry to hear that most of your Personal Vault files have disappeared.
Files in Personal Vault do not appear in the regular OneDrive search. Please unlock the Vault, open the OneDrive Recycle Bin, and select Show Personal Vault items to check whether the missing files are available for restoration.
For files that may not have been uploaded, Personal Vault cannot automatically search your computer. Please open File Explorer > This PC and search by filename or file type, such as *.pdf, *.docx, *.jpg, or *.xlsx. You should also check the OneDrive folder, Documents, Pictures, Downloads, Windows Recycle Bin, and any other computer previously connected to the account.
Before resetting, unlinking, or reinstalling OneDrive, copy any remaining files to a separate folder or external drive.
Unfortunately, if the files were never successfully uploaded and no local copies remain, OneDrive may not have cloud copies that can be restored.
Please feel free to let me know if you have any further updates, thanks.
