URGENT HELP LOSSS OF FILES MORE THAN 30 DAYS

For a personal OneDrive account, immediately search OneDrive.com, Personal Vault, every other Microsoft account, and all previously synchronized devices; if those checks fail, open a Microsoft Support case and explicitly request assessment for One-Time Data Restoration (OTDR) eligibility and a case/reference number.

1. Complete the remaining recovery checks

You have already exhausted the online Recycle Bin, so do not reset, unlink, reinstall, or resume synchronization on any device that might still contain photographs.

1. Search the OneDrive website directly
   • Sign in at OneDrive.com using a private/incognito browser window.
   • Select My files, then use Search everything.
   • Search using:
     • Several exact folder names.
     • Photo filenames or extensions.
     • Years, months, locations, tags, and descriptions.
   • Check Photos and manually inspect likely parent folders.
2. Check Personal Vault
   • Open Personal Vault and search or browse there separately; Personal Vault content does not appear in normal search results.
3. Check every other Microsoft account
   • Sign out and repeat the search using any other personal, work, or school account ever connected to your computers or phones.

These are Microsoft’s remaining documented checks for missing personal OneDrive files.^1^

4. Preserve and search every previously synchronized device
   • Windows: Pause OneDrive syncing, open File Explorer, search the former OneDrive folder and other drives for *.jpg, *.jpeg, *.png, *.heic, and camera filenames such as IMG_*; also inspect the Windows Recycle Bin.
   • macOS: Pause syncing, use Finder → This Mac, search by Kind: Image, and inspect Trash.
   • iPhone/iPad: Check Photos → Albums → Recently Deleted, the Files app, iCloud Photos, and any device backup.
   • Android: Check the gallery’s trash/recycle area, Files, DCIM, Pictures, SD cards, and any manufacturer cloud backup.
   • Check external disks, old computers, memory cards, NAS devices, and prior phone backups.

Pausing synchronization is only a precaution to protect possible local copies; it does not recover data from OneDrive. Copy anything found to a separate disk before reconnecting the device.

2. Open the support case and request OTDR assessment

Use Contact Microsoft Support, enter the issue, select Get Help, and then Contact Support when offered.^2^

Paste this request:

Please assess this personal OneDrive incident for One-Time Data Restoration (OTDR) eligibility and provide a case/reference number. Approximately 42,000 photographs in 33 folders disappeared around 2 October 2026 without an intentional deletion. The personal OneDrive Recycle Bin retention period had expired before discovery. Please record this as a suspected mass file-loss incident and advise whether any exceptional restoration or service investigation is available.

Attach or provide:

• The exact Microsoft account used, through the private support form only.
• Subscription type and storage usage.
• Missing folder names and representative filenames.
• Approximate last-known-good date and discovery date.
• Devices and OneDrive clients connected at that time.
• Screenshots showing the empty locations and Recycle Bin.
• Any mass-deletion, security, storage, or unusual-activity messages.
• A timeline of device changes, app installations, sync errors, or account alerts.

A closely matched accepted Microsoft Q&A answer recommends specifically requesting OTDR for personal OneDrive files missing beyond the normal recovery window.^3^ However, OTDR is not documented as an available personal-account recovery feature in Microsoft’s official recovery guidance, so eligibility and recovery are not guaranteed.

3. Understand the documented recovery limit

For personal OneDrive, deleted files are normally recoverable for 30 days, and Restore your OneDrive also rolls back activity only within the last 30 days. Microsoft states that files permanently deleted from the OneDrive Recycle Bin cannot be recovered.^4^^5^

Microsoft’s missing-file guidance also states that support agents cannot access files in a personal account or provide more recovery assistance than the published steps.^1^ Therefore, the support case should be treated as a request to:

• Determine whether any exceptional OTDR escalation is available.
• Document and report a suspected service incident.
• Obtain a formal case/reference number.
• Confirm the account’s recovery status.

It should not be assumed that Support can inspect a residual server copy or identify the deleting device.

4. Review account security

Personal Microsoft-account Recent activity shows only the last 30 days, so it will not establish what happened on 2 October if that date is now older than 30 days. It can still reveal newer suspicious access, including device/app type and approximate location.^6^

If anything is unrecognized:

1. Mark it This wasn’t me where available.
2. Change the account password.
3. Update security information.
4. Enable two-step verification.
5. Remove unrecognized trusted devices.
