Messageware is a Canada-based software company founded in 1993 that develops security and enhancement solutions for Microsoft Exchange Server, Outlook Web App (OWA), and Microsoft 365. The company operates as a Microsoft Gold Certified Partner and Global Exchange ISV, serving over 2,500 enterprises with more than 5 million users across 55+ countries. The company's product portfolio focuses on two core areas: security and usability enhancements for Microsoft messaging platforms. On the security side, Messageware provides capabilities including zero-day detection, defenses against high- and low-volume logon attacks, real-time threat identification, and analytics and reporting for Exchange Server environments. These tools are designed to protect OWA deployments from unauthorized access and credential-based attacks. On the enhancement side, Messageware offers products such as PlusPack, which extends OWA functionality to more closely replicate the desktop Outlook experience — adding features like spell check, multiple contact list access, personal signatures, and private distribution lists. Messageware partners with security vendors including RSA (for SecurID two-factor authentication interoperability), Spamhaus (IP and domain reputation data), Sophos, and Symantec to extend the security capabilities delivered to Exchange environments. The company's customer base spans government agencies, military and intelligence organizations, banking and financial services, law firms, pharmaceutical and healthcare companies, and educational institutions. Messageware is headquartered in Mississauga, Ontario, Canada.
