Dear Mohammed Irbaz,
Greetings! Thank you for posting in Microsoft Community.
I'm sorry that you encountered data loss issue after making changes to Microsoft 365 subscription plan. For the situation you encountered, we deeply understand the inconvenience caused and apologize for it.
Thank you for sharing with us the troubleshooting steps you have tried.
I understand you want to retrieve OneDrive and SharePoint data and ensure it's securely restored to your Microsoft 365 Business Essentials account. I believe the issue is related to the backend where it needs to further check by the related team.
Therefore, I sincerely recommend you raise a support ticket from the Office 365 admin center, where the related team will help you find out the cause of the problem and help you look for other ways from backend to recover your data.
Reference: Get support - Microsoft 365 admin | Microsoft Learn
Note: To create a support ticket, you need to have admin privileges and if you aren’t admin of your Office 365 organization, please contact the admin of creating a new ticket.
Apologies for redirecting you to the related team support as the moderators in this community have limited resources to check the backend information, and to get the fast and better assistance we requested for it.
Appreciate your patience and understanding. Have a great day!!
Sincerely,
Tina | Microsoft Community Moderator
