What MailStore Server is
MailStore Server is on-premises email archiving software for small and medium-sized businesses. It creates central copies of company email for long-term access and works with Microsoft 365, Google Workspace, mailboxes, email clients, and files. Archived messages can be searched through Microsoft Outlook integration or Web Access, then restored or exported as individual emails, folders, mailboxes, or a complete archive in EML, MSG, or PST formats. Retention policies, legal hold, logging, auditor access, journaling, and eDiscovery support are included. Integrated storage removes the need for an external database system, and the vendor says one installation can manage up to 2,000 users. SHA hashes and internal AES256 encryption help protect archived data. Windows 11 and listed Windows Server editions are supported, alongside an HTTPS management API with JSON responses. A Starter Kit for up to five users costs $259, paid once, excluding VAT, with 12 months of Standard Update & Support; a free 30-day trial is available.
