STRATEGIC PERSPECTIVE
The Unified Messaging Mandate: Protecting Corporate Communications in a Mobile World
Strategic Imperative: Enterprise communications cannot depend on vulnerable on-premise email servers; modern messaging requires carrier-grade cloud availability, military-grade encryption, and granular mobile ActiveSync governance.
Corporate email and mobile calendaring represent the foundational nervous system of modern business operations. Yet, many organizations continue to maintain legacy on-premise Microsoft Exchange servers (Exchange 2010, 2013, 2016) in private data centers. Operating on-premise email infrastructure exposes enterprises to catastrophic server hardware failures, complex storage area network (SAN) costs, unpatched Hafnium-style zero-day exploits, and unmanaged mobile devices accessing corporate inboxes without adequate endpoint encryption.
Routeget Enterprise Exchange & ActiveSync Practice designs and executes seamless cloud messaging transformations to Microsoft Exchange Online and Microsoft 365. Benchmarked against global enterprise standards, Routeget architects high-availability cloud messaging environments delivering 99.99% uptime SLAs, automated mailbox archiving, data loss prevention (DLP), and centralized mobile device management.
By implementing Microsoft Intune Mobile Application Management (MAM) policies for Exchange ActiveSync, Routeget ensures corporate emails, attachments, and contacts remain encrypted and isolated inside managed containers on employee iOS and Android devices, allowing immediate remote wiping of corporate data without wiping personal employee photos or applications.
