Very large loss of data.

Question

I urgently request the restoration of all files that were lost on February 4, 2026.

This is a very large volume of data, and I am unable to recover it manually.

These files are extremely important, and I cannot afford to lose them.

I kindly request that you verify and completely restore the data from that date.

Answer 1

Dear @Rafael Gonçalves,

I understand how important your OneDrive files are, and I truly empathise with how stressful it can be when files appear to be missing.

Based on the description, it seems the files were accidentally deleted about 27 days ago. Please note that OneDrive retains deleted items in the Recycle Bin for up to 93 days. Once this retention period expires, the files are permanently removed and are no longer recoverable through standard recovery options.

However, if the deletion occurred within the last 93 days plus an additional 14-day window, there may still be a possibility to recover your data by requesting a OneDrive site rollback. This option allows Microsoft Support to **restore your OneDrive to a previous state within the last 14 days.

**For reference, you may find this article helpful: How to recover missing, deleted or corrupted items in SharePoint and OneDrive for work or school - … 

For example: 

• Today is 3rd March so you can request to roll back your OneDrive to 19th Febuary (14 days prior). 

Once the rollback is completed, you should be able to find your files in the Recycle Bin or in their original location. 

To proceed with a restore request, please submit a support ticket through the Microsoft 365 Admin Center by navigating to Support > Help & Support, or directly via: from https://admin.microsoft.com/#/support/requests The Microsoft Support team over there has higher permissions and dedicated tools to investigate and correct escalation channels to handle this type of request, making this the most effective path to support your issue.

I hope the information above is helpful. If you have any further questions, please feel free to reach out.

It would be easier for us to assist if you can give some specifics on how you came to lose a lot of data.

Answer 3

For a very large loss of OneDrive data on a specific date, use OneDrive’s point-in-time restore instead of restoring files one by one.

Follow these steps (OneDrive for work/school or education):

1. Open OneDrive in a browser and sign in with the affected Microsoft 365 education account.
2. In the top-right corner of the OneDrive website, select Settings > Options (if shown) and then choose Restore your OneDrive.
3. On the Restore your OneDrive page:
   • Select the date closest to February 4, 2026 from the dropdown, or choose Custom date and time and set it to just before the loss occurred.
   • Use the activity chart and activity feed to review the actions from that date and confirm they match the mass deletion/changes.
4. Start the restore to undo all file and folder actions that occurred after that point (within the last 30 days of the restore window).
   • Be aware: any files or folders created after the restore point will be moved to the OneDrive recycle bin. They can be restored from there if needed.

If the loss is in a SharePoint-backed location (such as a Teams or class site library) rather than personal OneDrive:

1. Go to the affected SharePoint document library.
2. Use Restore this library (if available) to roll the library back to a previous time near February 4, 2026, or restore individual files via Version History.

If many files were deleted/overwritten and cannot be recovered via recycle bin or library restore:

1. An administrator can contact Microsoft 365 support and request a restore from backup (within the additional 14‑day backup window) for the affected site collection or library.
2. Provide support with:
   • The full URL of the affected OneDrive or SharePoint site/library.
   • Names of several affected files (with extensions).
   • The approximate date and time when the data was last in a healthy state (around February 4, 2026).

If the data loss is on a Windows Server protected with Azure Backup (MARS agent):

1. Open the Microsoft Azure Backup snap‑in on the protected server.
2. Select Recover Data.
3. Choose This server and the appropriate region.
4. Select Individual files and folders and pick a recovery point from February 4, 2026 (or closest available) to restore the deleted files back to the same machine.

If none of these options show the missing data (for example, it is not in OneDrive/SharePoint, not in recycle bins, and no backup/restore point covers that date), there is no additional native Microsoft method in this context to fully recover it.
