Legal Hold enables the preservation of a user’s edited and deleted mailbox items (email, appointments, tasks, etc.) from both their primary mailbox and Personal Archive. Legal Hold can be set on individual mailboxes or across the enterprise. They can also be set for a specific time period (for example, place a mailbox on hold for 90 days). In addition, Legal Hold includes an option that automatically alerts users through Outlook 2010 that a hold has been placed on their mailbox.
Multi-Mailbox Search enables search of mailbox items, including email, attachments, calendar appointments, tasks and contacts. Exchange also indexes a long list of attachment types as well as Information Rights Management-protected content. Multi-mailbox search can work simultaneously across primary mailboxes, Personal Archives and recovered items with an easy-to-use, Web-based console. To help streamline discovery processes, search results may be previewed with keyword statistics—before emails discovered through search are copied and moved to a specified mailbox, as defined by the administrator, for further investigation. Rich filtering capabilities include sender, receiver, message type, sent/receive date and cc/bcc, along with Advanced Query Syntax (AQS) support.
In Exchange, administrators can grant users such as records managers, compliance officers and litigators specific rights to perform multi-mailbox searches and other role-specific tasks.
