Our verdict on MailStore Server
MailStore Server is an on-premises email archiving application for small and medium-sized businesses. It centralizes messages from Microsoft 365, Microsoft Exchange Server, Google Workspace, MDaemon, IceWarp, Kerio Connect, IMAP- and POP3-compatible servers, and PST files. Users can search archived email through Microsoft Outlook or a web browser, restore messages, and export them in EML, MSG, or PST formats. It is intended for Windows organizations that need centralized retention and archive access.
Pricing is straightforward at the entry level. The Starter Kit costs $259 one time, covers up to five users, and includes one year of Standard Update & Support Service. A 30-day free trial is available, but there is no free plan. The product is deployed on-premises, so organizations should account for local installation and administration rather than expecting a hosted archive service. Its integration range suits environments that combine Microsoft 365, Exchange, Google Workspace, compatible mail servers, Outlook, or PST files.
The strongest fit is for teams that need more than message storage. Retention policies, legal hold, journal capture, auditing, company-wide archive search for eDiscovery, tamper-proof storage, and signed exports address compliance and investigation workflows. Archived email can be retained indefinitely by default, with configurable retention of up to 1000 years. MailStore Server is less suitable for organizations that require a cloud-only deployment, a free tier, or broader platform coverage than Windows. Those buyers should consider an alternative with those delivery and licensing priorities.
