Thank you for providing the additional details. Since you've followed all steps, including creating a new ADLS storage account with public network access enabled, and still face issues with data export from Purview, here are some additional steps to consider:
Verify Storage Account Configuration - Ensure that the new ADLS storage account is correctly configured to allow exports from Purview. Check if there are any specific policies or restrictions applied at the container level that might prevent data from being written.
Check Purview Export Jobs - Navigate to Monitoring > Export Jobs in Purview to see if there are any active or failed jobs related to the export. This will give insights into why data is not being exported.
Azure Monitor and Logs Analysis - Use Azure Monitor and review the logs for any anomalies or errors related to data export from Purview. Ensure there are no network or permission-related errors.
Purview Version and Updates - Ensure that both Purview and the underlying services (e.g., Azure Data Lake Storage) are up-to-date. Sometimes, updating Purview or any dependent services might resolve persistent issues.
Retry with Different Settings - Try changing the storage container or the destination path once again. Sometimes, a fresh configuration with minor adjustments can resolve export issues.
