Dear Amine BOUASSIDA,
Good day to you!
I hope you are doing well. Thanks for reaching out to our Microsoft Community Forum. We will be happy to help you.
I understand your concern—losing important data can be very challenging. Since you mentioned that you’ve deleted the file from the recycle bin as well, have you checked the second stage recycle bin? When files are deleted from the recycle bin, they are stored in the second stage recycle bin. You can find the second stage recycle bin at the bottom of the recycle bin page.
If you don’t find the data, have you tried restoring your OneDrive with custom date? via go to your OneDrive> click on settings icon top right corner > Click on Restore your OneDrive > Click on Select a date Dropdown option > Select Custom date and time > Select the item and Click on Restore.
For data loss scenario, as community forum, we have limited resources, however, Microsoft have a dedicated support team equipped to handle such issues. I recommend contacting Microsoft support for assistance. They have the expertise and tools to help you recover your data. Here’s the support document with contact details: Get support - Microsoft 365 admin | Microsoft Learn. Additionally, if you are part of an organization, your Microsoft administrator can generate a support ticket through the admin portal. For convenience, here is the portal link: Microsoft 365 Admin Center. Please understand for data loss, the data can be recovered from Microsoft side within 14 days after deleting.
I do apologize for any inconvenience.
Thank you for your understanding. Your patience and cooperation are greatly appreciated.
Best Regards, Nahid Sultan
