Hi @IniobongNkanga-8038 ,
You can Select the Run Tests: Invalid Retention or grace eDiscovery Hold button to populate the associated test in the Microsoft 365 admin center
In the Run diagnostics section, either type or copy and paste the URL of the SharePoint or OneDrive site that you want to delete.
If the test finds an invalid retention policy that might be blocking the deletion, you can choose to remove the policy.
If the test finds that the eDiscovery hold is within the 30-day grace period, you can choose to remove the hold.
Here is the document for reference
