Email Archiving

Searchable retained copies of inbound and outbound email for compliance and e-discovery.

"Securely stores and retains email communications, helping organisations meet compliance requirements and access historical data when needed."

Searchable email retention and archiving for compliance and e-discovery

Keeping an auditable, searchable record of organisational email is a frequent operational burden. Teams must meet retention rules, respond to legal or regulatory discovery requests and keep exports for records without disrupting live mailboxes.

Hornetsecurity Email Archiving stores and indexes inbound and outbound mail and attachments so messages can be searched, retrieved and exported. That gives control over retention enforcement and provides a retained copy for searches and production across an estate.

Where Email Archiving is used

Retention enforcement: apply and demonstrate retention policies by retaining a separate, searchable copy of email across domains and subsidiaries. This helps where live mailbox retention might be changed or users delete messages.

E-discovery and export: perform targeted searches across retained mail, collect message sets and export them for legal review, regulatory requests or records management processes. Works for estates using Microsoft 365 and mixed domain setups.
