Case Study

Improved oversight of pharmaceuticals' global tenant

Effective tenant management structures and reporting deliver time- and cost-savings, as well as improved security, for our global pharmaceuticals client.

Client: Global pharmaceuticals company


  • 9,800+ employees
  • 71 offices in over 50 countries
  • Global supply chain to over 150 countries
  • More than 26,000 Microsoft 365 objects
  • Highly regulated industry


  • Considerable time-savings through automated onboarding and streamlined reporting capabilities
  • Cost-savings from improved tenant management structures and detailed reporting
  • Better oversight and tighter security to identify and eliminate gaps
  • Ongoing relationship aligning business needs and feature development

The challenge

Having evolved from a federated IT management model to a more centralised, Office 365 platform, our client needed to consolidate multiple tenants into a single platform. They also needed the ability to limit administrative control within their various regions through “sub-tenanting”, while maintaining global control, and not releasing full access to all Microsoft 365 objects.

‘The level of enthusiasm and willingness to support us with regards to the contracted services from Cloud Essentials is second to none. They are just as supportive from a project and professional services standpoint as some of the most knowledgeable individuals in the ‘365’ space’.

Our solution

Specialist migration design

We entered this project with a good understanding of the client’s operating challenges and Microsoft 365 landscape, having already assisted them with complex migrations and ongoing support. After reviewing their needs and challenges, and drawing up a detailed design document, we selected Coreview as the best-fit project partner. Their specific toolset would enable us to optimise a multitude of business areas, particularly around user provisioning, user management, license management, and workflow optimisation.

Expert set-up

We assisted the client with the installation of Coreview. We then configured the hybrid server component and virtual tenant to make available greater business efficiencies, automated work processes and improved reporting capabilities. This included configuring the system to allow specific business unit operators to manage their user base, limiting them to only view their users and objects.

We configured licence pools, built in permissions, and created workflows. We also used our on-premises and cloud knowledge to build reporting solutions within the Coreview platform.

We then provided the client with general training to familiarise them with the console and navigation, as well as in-depth training for specific roles and requirements.

Tailored customisation and development

We have a very good working relationship with Coreview and were able to work with them to tailor their product development to suit our client’s needs and recommendations/advances.  

Transparent communications

Daily meetings with the technical team and weekly meetings with key stakeholders kept the project on track.

“Through a collective effort, we overcame environmental challenges and managed to deliver a successful tenant to tenant migration of multiple workloads with minimal impact on the users, in keeping with timescales and solidified an excellent working relationship with the client”

The Result

Cloud Essentials continues to provide our client with progressive feedback and optimisation sessions, maintaining the alignment of their business needs and feature development.

We’ve saved them considerable time using workflows to automate onboarding and reporting. We’ve also successfully reduced their costs by: establishing virtual tenants as licence pools; mapping business units as cost centres; performing AD integration; maximising licence management through reporting that uncovers disabled users and unused licences.

Cloud Essentials’ experts also designed a number of reports in Coreview to perform clean ups, monitor licence allocations and anticipate future requirements. Our client now has better oversight and tighter security.
