MailStore

MailStore helps you take full control of your company's email data by creating 1:1 copies of all emails in a central archive. You can secure large volumes of data permanently while meeting complex legal retention requirements and GDPR obligations. By offloading emails from your active server to the archive, you significantly reduce the workload on your IT infrastructure and eliminate the need for unreliable PST files.

You can empower your team with lightning-fast full-text searches for emails and attachments, accessible directly through Outlook or a web browser. Whether you use Microsoft 365, Google Workspace, or an on-premise Exchange server, the software integrates into your existing environment. It is specifically designed for small and medium-sized businesses looking for a reliable way to prevent data loss and simplify backup processes.
