How this will affect your organization

With one click, end users will block emails from unwanted senders and prevent those emails from showing up in their default quarantine view and in their quarantine notifications. If no admin overrides exist, end users will also be able to allow emails from trusted senders and prevent future emails from those senders from going into quarantine. End users can now review admin any override reasons that lead to quarantined emails.
