Where Microsoft’s own pages disagree

  • Microsoft 365 E7: the Swiss comparison table doesn’t show clearly which Intune Suite items (Remote Help, Enterprise App Management, Endpoint Privilege Management, Advanced Analytics, Cloud PKI, Plan 2) are included; Microsoft’s pricing update says the E5 packaging changes apply to E7 too.52
  • Naming: Microsoft Learn (17 September 2026) calls the products “Microsoft Copilot” and “Microsoft Copilot Business”, while the Swiss and US pricing pages still say “Microsoft 365 Copilot” and Microsoft’s licensing list still says “Microsoft Copilot for Microsoft 365” (Microsoft_365_Copilot).789
  • Switzerland isn’t in the EEA, yet Microsoft’s Swiss pages sell “EWR” (EEA) suites without Teams. The Swiss price gaps between with and without Teams (about CHF 6.93 for enterprise suites, 2.61 for Business, 1.30 for Business Basic) differ from the euro minimums Microsoft committed to the European Commission (EUR 8.00 / 3.00 / 1.50).510
