r/AI_Agents: Developer Who Deployed Microsoft Agent 365 for Two Weeks Finds Blueprints Half-Implemented and Entra Agent Identity Broken in Practice

A developer who spent two weeks attempting a real Agent 365 deployment—Entra Agent ID registration, blueprint configuration, and Agent 365 registry onboarding—reports widespread gaps between marketing claims and actual product behavior: blueprints are incomplete, agent identity persistence breaks across sessions, and error handling in the Entra flow is opaque. Community comments confirm the experience is widespread, with multiple builders noting the contrast between KPMG's widely cited 470,000-seat deployment narrative and actual enterprise onboarding friction. The post is gaining traction as Agent 365 enters broader enterprise procurement evaluation cycles.
