Unlock the Personal Vault from OneDrive’s web Recycle Bin first, because deleted Vault files remain hidden there until Show Personal Vault items is selected.
Recover the Personal Vault files
- Sign in at OneDrive.com using the Microsoft account that owns the 1-TB subscription.
- Select Recycle bin in the left navigation.
- Select Show Personal Vault items and complete the identity verification.
- Select the missing documents, then select Restore. Personal-account files can normally be restored from the Recycle Bin within 30 days, unless they were permanently deleted. ^1^
- Open My files → Personal Vault and verify that the documents have returned.
Personal Vault documents do not appear in OneDrive search results, so searching by filename cannot confirm whether they still exist in the Vault. Also check that the browser is signed in to the correct Microsoft account, especially if multiple personal, work, or school accounts are used. ^2^
If the entire Vault was emptied recently
Because the account includes Microsoft 365 storage, restore the whole OneDrive to a point before the documents disappeared:
- On OneDrive.com, select Settings → Options → Restore your OneDrive.
- Choose Yesterday or Custom date and time.
- Use the activity chart to locate the deletion or other unexpected activity.
- Select the earliest activity to undo, review everything selected after it, and choose Restore.
This can reverse file and folder changes made during the previous 30 days. Caution: files created after the selected restore point move to the Recycle Bin, where they can be restored separately. Permanently deleted Recycle Bin items cannot be recovered. ^3^
Reach a Microsoft support agent
Since the chatbot did not help, use Microsoft’s technical-support contact page:
- Open Contact Microsoft customer support.
- Select the Personal account tab.
- Under Microsoft technical support, select Get help.
- Enter:
“OneDrive Personal Vault suddenly empty. Recycle Bin and Restore your OneDrive checked. I need a technical support agent.”
- Select the offered contact option, which may include live chat. Available options depend on the product, subscription, region, and time. ^4^
Have the approximate date the files disappeared, the last device used, and several filenames ready. Do not post account details publicly.
Microsoft support can investigate the account or service issue, but agents are not permitted to open or access the contents of personal files. If the files are absent from the unlocked Recycle Bin, outside the 30-day restore window, and permanently deleted, Microsoft documents no additional recovery method. ^2^
