Archive Mailbox with eDiscovery and legal hold for defensible preservation and search

Mimecast pairs email archiving with governance controls that route messages into retention policies and make them searchable for legal and audit teams. Archive Mailbox stores and indexes email content and metadata so investigations can start with defensible search and matter-relevant results. Legal hold and eDiscovery workflows support preservation of specific mailboxes or mail streams, and audit logging records administrator and user actions for traceable review trails.

A key tradeoff is that archive and governance configuration requires careful policy design so retention rules, hold scope, and access permissions match internal legal requirements. Some organizations also experience increased operational overhead when migrating existing archives into the same discovery and governance workflow. Mimecast fits best for regulated environments where investigators need repeatable search results, hold enforcement, and exportable evidence instead of ad hoc email searches.
