The Barracuda Cloud Archiving service is part of the Premium Plus pricing plan. It is a cloud-based solution that captures an accurate and unmodified copy of emails as they are sent or received. The service keeps copies of these emails as per policies/compliance requirements. Barracuda Cloud Archiving is performed directly from Office 365. The solution also offers PST management for legacy email, uses granular retention policies, offers a full text search, and helps with regulatory compliance.
