How a 43,000-Person Insurance Firm Controlled Microsoft 365 License Sprawl Without Losing Admin
SUMMARY
  • A large national insurance brokerage was struggling with  Microsoft 365 license overuse and rising costs because allocation was managed manually across a 43,000-seat tenant.
  • CoreView helped the firm create  division-level license pools and scoped admin environments, giving each division controlled autonomy without exposing tenant-wide settings or other divisions’ data.
  • By combining  Virtual Tenants, license governance, ServiceNow integration, and workflow automation, the firm reduced central IT bottlenecks, prevented overconsumption, and executed around  35,000 automated workflows in 90 days.

Microsoft 365 Management at 43,000-Employee Scale

A national insurance brokerage with more than 43,000 employees operates across four divisions and dozens of distributed offices. At that scale, managing Microsoft 365 manually stops being inconvenient and starts costing real money.

Challenge: License Overuse and Central IT Bottlenecks

The firm had two connected problems.

First, license allocation was managed manually across a 43,000-seat Microsoft 365 tenant. At that size, manual management meant overconsumption was going unchecked, and unnecessary costs were accumulating.

Second, centralized administration across four divisions was creating IT bottlenecks. With admin requests from distributed offices being funneled to a single team, tasks were missed and response times were slow. The firm needed division-level admin capability, but not at the cost of tenant-wide security.

Microsoft 365’s native tooling does not give organizations enforceable boundaries by division. Without a mechanism to cap consumption per division, allocation is reactive. The firm would be discovering overuse after it happened, rather than preventing it.

Delegating administration natively meant choosing between granting division staff broader tenant access than appropriate, or keeping everything central and living with the bottleneck. Neither worked for a four-division organization of this size.

Solution: Controlled Licensing, Scoped Admin Access, and Workflow Automation

The insurance brokerage deployed three CoreView capabilities.

  • Licensing - Licenses are now allocated to each division through license pools with defined limits. Divisions can consume up to their allocation. Overconsumption is prevented structurally, not caught after the fact. The firm can account for every seat.
  • Administration - CoreView’s Virtual Tenant capability gives each division its own scoped admin environment within the single Microsoft 365 tenant. Division admins handle requests and manage users within their own boundary, without visibility into other divisions or access to tenant-wide settings. Central IT keeps full oversight.
  • Workflow automation - The firm leans heavily on CoreView’s ServiceNow integration, combining Playbook-driven remediations with ServiceNow request handling. In the past 90 days, the firm executed roughly 35,000 of these automated workflows.

Tasks that previously required central admin handling are now resolved at division level. The queue is shorter, and fewer tasks are missed.

Results: Division-Level Autonomy Without Tenant-Wide Risk

The firm now has license consumption that is visible, bounded, and enforceable across all four divisions. Administration is distributed to the people who own the work, without distributing the risk that comes with it.

Those were the two problems the firm came in with. CoreView helped address both: controlling license consumption by division and giving local teams the ability to act without expanding tenant-wide risk.
