Messageware OWA Desktop is a client-side application for Microsoft Windows that integrates Microsoft Outlook Web App (OWA) functionality directly into the desktop environment. It enables OWA to function as the default mail client, providing a desktop-like experience for users of OWA with Exchange or Office 365, and can address functional limitations found in certain Office 365 tenant plans. The application is designed to bridge the technical gap between browser-based email and native desktop clients.
Operating from the Windows system tray, the application manages automated logons to maintain continuous session connectivity to the mail server. It generates real-time, interactive pop-up notifications for new emails and calendar events that overlay other active windows. This allows users to access messaging and scheduling functions without needing to keep an OWA browser window open or active, providing access to mail and calendar information via the system tray.
