Can I recover deleted data in CORE?

No. Deletion of data in BQE CORE is permanent and cannot be undone. When a project, email, or any other record is deleted, it is permanently removed from the system and cannot be recovered through CORE. To avoid accidental loss, you can export critical emails or data externally, or confirm carefully before deleting any item. Permanent deletion is intended to ensure data integrity and performance in CORE. 

As a good practice, you can void data to leave a trail or make it inactive in case you want to revisit it later.
