Consolidating three Microsoft 365 tenants into one for a construction group to improve collaboration, security and cost efficiency.

A strategic migration that improved collaboration, reduced costs, and strengthened security across multiple organisations.

04 Nov 25

Managing multiple Microsoft 365 tenants can quickly become a headache, especially for organisations with several subsidiaries. For a group of construction companies, this meant inconsistent standards, patchy configuration, and spiralling costs. We delivered a unified tenant structure that simplified management and enabled growth.

The Challenge

Multiple tenants meant multiple headaches: inconsistent Intune policies, scattered Entra ID configurations and no centralised governance.

Our Approach

We designed and implemented a single Microsoft 365 tenant under the holding group; creating a robust, scalable foundation for all organisations. Key steps included:

  • Tenant consolidation into one unified environment
  • Domain alignment for each subsidiary under the group structure
  • SharePoint architecture tailored for multi-organisation collaboration
  • Entra ID and Intune policies targeted by user groups for precision control
  • Zero Trust security model applied across SharePoint and Entra for maximum protection

Real-World Impact

The benefits were immediate and measurable:

  • Simplified billing and predictable cost management
  • Reduced support hours thanks to centralised administration
  • Improved internal collaboration. No more B2B-style barriers
  • Aligned security and compliance standards across all entities
  • A future-proof tenant structure ready for growth
