HexaCorp successfully migrated a mid-sized global organization from an aging on-premises Exchange Server to Microsoft 365, enhancing their communication, collaboration, and security capabilities. This migration addressed performance issues, reduced infrastructure costs, and provided a scalable, cloud-based solution tailored to meet the client’s evolving needs. The project included the migration of 500 users, implementation of advanced security measures, and a seamless transition to a fully cloud-based email system, Microsoft Exchange Online.

• The on-premises Exchange Server was aging, leading to performance and security concerns.
• The client faced high maintenance costs and limited scalability with their existing infrastructure.
• There was a need for a flexible, cloud-based solution to support a growing, mobile workforce and enhance collaboration.
• The client required advanced security and compliance features to protect sensitive data and meet industry standards.

• A thorough audit of the client’s Exchange environment identified challenges and guided the migration strategy.
• Implemented a hybrid Exchange Server and Exchange Online deployment to ensure a seamless transition without interrupting email services.
• HexaCorp migrated mailboxes, calendars, and contacts to Exchange Online in batches, using Azure Active Directory for user authentication.
• Configured Microsoft 365’s advanced security features such as multifactor authentication, encryption, and data loss prevention (DLP).
• Decommissioned the on-premises Exchange Server and optimized the environment to ensure a smooth and secure transition.
