How a global insurance broker unified Microsoft 365 after acquisition

The Challenge

The organisation operated across multiple Microsoft 365 tenants. This created administrative complexity, fragmented collaboration and a reliance on guest access. A large legacy SharePoint environment, with more than 145,000 sites and 7 TB of data, added significant technical and delivery risk.

The Solution

bluesource consolidated the separate Microsoft 365 environments into a single global tenant. Exchange Online, OneDrive and SharePoint Online were migrated to simplify access and collaboration. A complex legacy eFiling platform was isolated and re-architected, reducing programme risk and supporting future migration activity.

The Result

The organisation now has a unified Microsoft 365 platform that supports more consistent collaboration, stronger governance and lower operational overhead.

Key Business Outcomes

  • Simplified Microsoft 365 administration and governance
  • Improved user access and collaboration across the organisation
  • Reduced operational complexity and support overhead
  • Lowered platform and migration risk
  • Created a scalable foundation for future growth and transformation
