To address the performance degradation and service limitations of its legacy email system, our client, a leading financial services organization in UAE, partnered with Intertec to migrate its email infrastructure to Microsoft 365. This strategic migration encompassed over 600 end-user and functional mailboxes, distribution lists, and room mailboxes—achieved with zero disruption to business operations. The project not only restored seamless communication but also introduced modern security and user self-service capabilities.
Business Problem
The client’s legacy Exchange email system had become a source of repeated service outages due to its outdated version and lack of OEM support. Microsoft had implemented throttling policies, capping email delivery to just 30 minutes per hour, severely impacting the organization’s ability to send and receive critical communications. These disruptions not only risked operational delays but also hindered customer engagement and internal workflows.
How Intertec Helped
To overcome the risks posed by the outdated on-premises Exchange system, Intertec designed and executed a strategic migration plan in close coordination with the client’s Project and BAU (Business As Usual) teams. The initiative covered several key areas:
- Email Infrastructure Modernization: Successfully migrated over 600 end-user and functional mailboxes, 300+ distribution lists, and room mailboxes to Microsoft 365.
- Zero Disruption Execution: Planned and performed the migration with minimal impact on daily operations and without exceeding bandwidth limitations.
- Legacy Isolation: Decommissioned outdated Exchange servers, fully isolating them from the client’s production environment to eliminate lingering vulnerabilities.
- Security Reinforcement: Implemented Mobile Application Management (MAM) policies, allowing access to Microsoft 365 only via domain-joined and compliant devices—restricting personal devices from accessing corporate data.
- User Empowerment: Rolled out Self-Service Password Reset (SSPR), enabling users to manage their own credentials and reducing dependency on IT support.
- Operational Collaboration: Maintained close coordination with business stakeholders to align the migration plan with operational continuity goals.
Business Outcomes Delivered
The move to Microsoft 365 enhanced reliability, security, and user experience—delivering clear, lasting benefits:
- Seamless Migration: Zero downtime migration to Microsoft 365, ensuring uninterrupted email services during the transition.
- Enhanced Communication: Restored full inbound/outbound email delivery performance, resolving throttling-related delays.
- Improved Security Posture: MAM policies ensured only authorized devices could access corporate data.
- Empowered End Users: Self-Service Password Reset (SSPR) streamlined support and reduced helpdesk load.
- Future-Ready Infrastructure: A scalable, secure, and cloud-based email platform aligned with modern collaboration needs.
