In their own words
MessageSolution Enterprise Email Archive
MessageSolution Enterprise Email Archive is an email archiving and eDiscovery platform for compliance, litigation support, and storage management. It lists support for Microsoft Exchange, Exchange Online, IBM Lotus Domino, Google Mail, Novell GroupWise, and Linux/UNIX email servers. An existing journal mailbox can capture inbound and outbound messages before users can delete them. The built-in full-text search engine and database do not require a SQL server, according to the product page. Litigation tools include legal hold, classification, tagging, annotations, message pathway analysis, and authenticity verification. Deployment choices include cloud, on-premise installation behind a customer firewall, and hybrid arrangements. Archive access is listed through a browser, Outlook, Lotus Notes, OWA or DWA, and offline access; the feature matrix also lists Mac and iOS access. Administrators can configure retention, filtering, storage, and stubbing policies and review activity reports. The vendor says compression and single instance storage reduce email storage by an average of more than 75%. Pricing is on request, with a maintenance minimum of 600 USD per year. Nonstandard or modified email server environments may require weeks or months of customization and engineering fees.
Open Archiver Enterprise
Open Archiver Enterprise keeps company email searchable and tamper-evident on infrastructure controlled by the organization. It connects to Google Workspace, Microsoft 365 and IMAP, and can import PST, EML and MBOX files in bulk. Enterprise journaling records unmodified messages for each recipient, including BCC recipients, alongside mailbox synchronization. Full-text search covers email and attachments, with EML export and eDiscovery tools. Retention policies, legal holds, a hash-chained audit log and integrity reports support GoBD and GDPR-related workflows. Security options include AES-256 encryption for archived files, OIDC and SAML single sign-on, group role mapping from an identity provider, and organization-wide two-factor authentication policies. The vendor says email, the index and encryption keys remain on customer-controlled servers; messages are stored as plain.eml files. The self-hosted open-source edition is free. Enterprise is a perpetual, one-time license per archived mailbox, listed at €14, paid once. The first year of updates and support is included; after that, the license and features continue, but updates and technical support stop.
