Enforce Granular Email Retention Policies and Legal Holds Barracuda Essentials lets you automatically archive all your email, or only those emails that are relevant, by establishing granular policies based on sender, recipient, keyword, date, and more. You can set up retention policies ensure that an accurate and fully compliant copy of every email sent or received will be retained for the entire period required for that specific data. You can apply legal hold to specific archives, either manually or automatically via policy. Emails that are under legal hold cannot be altered, and you can also limit access by user or group. Legal hold can be set for a specific time period, or until you remove the hold. Simplify E-Discovery and Searching E-discovery requests can be a costly interruption, requiring skilled technical staff to dedicate time and effort to searching for relevant messages. Regulatory audits can be similarly harmful to productivity. And day-to-day activities by employees in all roles can be slowed down when archived emails are not easily found and retrieved. Essentials extends the familiar, intuitive search functions of Exchange and Office 365 across all archived messages. For ordinary users, searching and retrieving archived email virtually indistinguishable from a normal inbox search. For auditors, complex e-discovery can be accomplished quickly and easily with no special technical skills. Search parameters can be saved and reused, and individual messages returned in the results can be tagged for easy classification. Locate, Migrate, and Eliminate PST Files Before Office 365, many important emails were stored in PST files, personal archives used by end-users that are typically scattered across many devices and network storage. It can very difficult to locate all of these PST files and migrate them to a central archive. PST Enterprise automatically discovers PST files wherever they exist across your organization, by scanning end-user devices and network servers. It then migrates data from these files to a secure location such as Exchange or Office 365, or archives data to the Barracuda Message Archiver or Barracuda Cloud Archiving Service.
