The E5 shelfware report Microsoft’s account team hopes you never see

This is not a feature comparison. It’s a data-driven shelfware analysis based on 200+ enterprise E5 assessments — with three alternative licensing architectures that deliver the security and compliance features you actually need at 30–45% less cost.

📊

E5 Utilisation Benchmarks

Feature-by-feature utilisation rates across 200+ enterprises. Which E5 products are actively used (7 median), which are shelfware (55 median), and how much the waste costs per seat per month ($14.20 average).

4-Layer Shelfware Audit Methodology

Licence assignment vs. active use, feature-level adoption analysis, user segmentation by requirement, and cost impact modelling. The complete methodology for quantifying your E5 waste and building the rationalisation case.

6 Reasons Orgs Buy E5 (And Shouldn’t)

The security fear sell, bundle economics illusion, compliance mandate misinterpretation, Phone System bundling trap, “future-proofing” fallacy, and seller incentive misalignment. Each debunked with data.

3 Alternative Architectures

E3 + targeted add-ons (30–40% savings), E3 + third-party security (35–45% savings), and mixed-SKU E5/E3/F3 (25–35% savings). Each with blended cost models for a 10,000-user organisation.

6 Contract Protections

Annual SKU downgrade rights, add-on procurement flexibility, mixed-SKU discount preservation, bi-directional seat adjustment, Copilot decoupling, and architecture change protection.

Vendor Independence Guarantee

100% independent. Zero Microsoft partnership. No resale, no competencies, no partner incentives. Based on 200+ E5 shelfware assessments. Every recommendation in your interest — not Microsoft’s.

The average E5 deployment actively uses 7 of 62 included products. The remaining 55 products — representing 65–72% of the E5 premium — sit as shelfware: licensed, paid for, and unused. For a 10,000-seat deployment, that is $1.7M per year in waste.
