Email Archiving
Email archiving is the systematic capture, retention, and indexing of email messages and their attachments as records, preserving content and metadata so messages remain authentic, searchable, and disposable on schedule.
Email archiving is the practice of automatically capturing email messages, attachments, and their associated metadata into a managed, tamper-evident store so they can be retained, searched, and disposed of according to a retention schedule. It matters because email is a primary system of record for decisions, approvals, and transactions, yet live mailboxes are routinely deleted, quota-purged, or altered by users, putting genuine records at risk. A sound archive preserves transmission metadata (sender, recipients, timestamps, message IDs) and the message body intact, supporting authenticity, e-discovery, and litigation holds that must override normal disposition. Email archiving is distinct from simple backup: backups exist to restore systems after failure and are not organized by record value or retention rules, whereas archiving classifies messages, applies retention, and enables defensible deletion. For electronic recordkeeping standards, note that NARA revoked its DoD 5015.2 endorsement in 2022 and now points agencies toward the Universal Electronic Records Management Requirements and the FERMI program for capability expectations.
