For a Microsoft-stack enterprise in 2026, Microsoft 365 Copilot Agent Mode is the lower-friction agent-platform choice if the workflow already lives in Microsoft Graph; it is structurally weaker on multi-vendor deployment, model-portability, and platform-independence than dedicated agent platforms (Anthropic Managed Agents, OpenAI Agents SDK, Vertex AI Agent Builder). The procurement decision turns on three questions: (1) is the workflow Microsoft-resident, (2) is multi-vendor model selection a hard requirement, (3) is the agent's primary surface productivity-suite or workflow-orchestration.
Microsoft-stack reader piece. No prior dedicated coverage of M365 Copilot Agent Mode in the corpus despite ~60% of target audience running Microsoft-heavy stacks. Cadence 60-day. Trigger conditions: Microsoft expanding Foundry Agent Service capabilities materially; pricing changes to Copilot for M365 (currently $30/user/month); BAA/data-residency posture shifts; new MCP-server integration that closes the multi-vendor gap. Sister claims: AM-141 (Agent Mode pillar), AM-003 (GPT-5 Pro), AM-125 (ServiceNow Now Assist). Inline sources: Microsoft 365 Copilot pricing page, MS Learn agents documentation, EU Data Boundary.

About this register
The Reporting register tracks claims published from articles addressed to senior enterprise IT leaders — CIOs, IT directors, heads of platform. Claims are reviewed on a 30–90 day cadence; each review either reaffirms the claim, marks one substantive part as Partial, or marks it Not holding once the underlying evidence has been overtaken.

Pricing/model drift: a $100/mo Pro tier now sits beside the $200 tier (added 9 Apr 2026) and the premium model is GPT-5.5 Pro. Core thesis holds; the single-$200-tier framing no longer matches. Re-verify current tiers at chatgpt.com/pricing.

URL state changed. The /the-agentic-ai-revolution-real-world-success-stories-and-strategic-insights-from-2024-2025/ slug now serves a deliberately rewritten retrospective (claimId AM-130, "Agentic AI 2024-2025 retrospective", published 04 May 2026) against audited primary sources. The 28 Apr 2026 redirect to /retractions/ has been lifted to allow that. AM-002 the claim remains Not holding — the original $3.50/dollar + 70% failure-rate framing was withdrawn and is not restored. AM-130 is a separate claim with its own evidence chain. Readers arriving at /holding/AM-002 see the withdrawal here; the article link surfaces the new piece at the URL the original lived at, with this entry as the audit trail.

Klarna walk-back primary-source upgrade — added Siemiatkowski verbatim quotes via Bloomberg-cited-by-Fortune (9 May 2025) and the Uber-style freelance hiring detail via Entrepreneur. Closes the highest-priority evidence gap from the source dossier.
