A Microsoft file hosting and synchronization service.
Direct escalation or contact initiation with Microsoft support engineers is not possible.
To move this forward, use the official support channels and provide the existing case number and data-loss details so the case can be reviewed and escalated:
- If this is OneDrive for work or school
- Contact the Microsoft 365 admin in the organization and ask them to open or escalate a service request with Microsoft 365 support, referencing the existing case number and confirming this is a data-loss incident.
- When the admin contacts support, they should provide:
- The existing case number.
- The full URL of the affected OneDrive or SharePoint library (for example:
https://contoso.sharepoint.com/sites/<SiteCollectionName>/Shared%20Documents). - Names of several affected files/folders and their extensions.
- The approximate date/time the content was last in a good (uncorrupted) state.
- If files cannot be recovered via Recycle Bin or Files Restore, SharePoint Online/OneDrive for work keeps backups for 14 additional days beyond deletion. Within that 14‑day window, an administrator can explicitly request a restore from backup for the affected site collection.
- If this is OneDrive for home (consumer)
- Use the Microsoft Support site and choose the consumer OneDrive support path, then:
- Start a new support request and clearly state that there is an existing case that is inactive.
- Include the existing case number, the approximate deletion date, and that Recycle Bin and Files Restore have already been tried.
- If files are not found in search or the OneDrive Recycle Bin, they usually cannot be retrieved. Support may still review the case, but native recovery options are limited once Recycle Bin and Files Restore are exhausted.
- Use the Microsoft Support site and choose the consumer OneDrive support path, then:
- Information to prepare for support or escalation
- Case number and tenant/account type (work/school vs home).
- Names of missing files/folders and, for photos/videos, when they were taken.
- Approximate last access date and which device was used.
- Confirmation that:
- OneDrive web Recycle Bin has been checked.
- Files Restore has been attempted (if available for the account type).
If the current case remains inactive after using the official support contact paths, open a new support request and reference the old case number, clearly marking it as a data-loss incident requiring review by the appropriate support tier.
