UbiStor’s MailStor email archiving system is the industry leading software solution for the small-to-medium size business and remote office back office markets.  It ensures that all emails are captured and encrypted and securely and accessibly stored in compliance with alregulatory requirements by providing a unique and integrated set of software services that are unequaled and unparalleled by any other company in the world today.   

MailStor is a standalone, server agnostic, full-featured email archiving solution for Microsoft Exchange Server (2000, 2003, 2007, and 2010) that is deployable within a server, virtual server, appliance, or as a SaaS model in an MSP environment.  Its industry leading patent pending feature Continuous Archiving allows you to capture all emails in all cases even when your exchange server is down for any reason at all.

The MailStor solution employs enhanced stubbing methodologies that can be used to reduce the size of the Microsoft Exchange Server by up to 80%.  Stubbing can be configured to remove message contents and attachments from all users or a select group of users of an email archive within a company.  The stubbing controls will flexibly allow a company to gain optimal control of the exchange environment.  MailStor seamlessly integrates with Microsoft Outlook to allow users to access all archived emails without the need for additional plug-ins or client side integration, and users can retrieve, reply, and forward contents directly from the MailStor archive without encumbering the exchange environment in any way.

The solution allows one archive server to archive all emails from all users in multiple domains of all types whether they are local or completely remote.  Users from all non-local domains can authenticate and login to the web console through either a VPN or a cloud and users in an entire company can access emails that are stored on more than one Exchange Server.  MailStor also comes with a PST utility that eliminates PST file proliferation across an enterprise, thereby improving email management, storage capacity and security, and retention control policies.

The MailStor solution provides a simple, efficient, secure, and easy-to-use eDiscovery solution for searching through and retrieving from email archives.  It is ideal for legal pre-processing and litigation support, by allowing advanced search, extensive reporting, multiple-case management combined with exporting capabilities, and the ability to invoke litigation hold.  The product meets many regulatory compliance and industry defined retention policy requirements such as Sarbanes-Oxley, HIPAA, Gramm-Leach-Bliley, SEC requirements, and many other worldwide governmental regulations.

The MailStor system is the only fully integrated, robust, and standalone solution that is available that can provide flexible and unmatched capabilities for your email archiving needs for your Microsoft Exchange environment.  The MailStor suite provides archiving, replication, backup, migration, and disaster recovery services that no other company can offer.  The entire MailStor system can be implemented in phases as the system is installed once and  features and functionality can later be unlocked at your company’s discretion through license keys.  Thus, it can be flexibly combined into an integrated architecture that is unique and unmatched in functionality and scalability by any other software solution.
