MP.AIGOV.1005 Classic Copilot Studio service principal has no corresponding Agent ID registration (Preview)
[!NOTE] Validated 2026-11-05 against a real Microsoft 365 test tenant (Graph only, no Agent 365 license). The run passed clean: no classic Copilot Studio service principal in the test tenant was missing an Agent Identity or Blueprint Principal registration.
Checks for classic Copilot Studio service principals — tagged AgentCreatedBy:CopilotStudio,
AgenticApp, AIAgentBuilder, AgenticInstance, or a power-virtual-agents-* tag — that have no
corresponding Agent Identity or Agent Identity Blueprint Principal registration. This describes a
current state, not a required migration: Microsoft has not published an in-place way to convert a
classic service principal into an Agent ID.
Graph only — this test does not need a Microsoft Agent 365 license.
Remediation action
For each flagged agent, decide its disposition: retire it if unused, recreate it with Agent ID if lightly used, or keep it running as-is (with its own sponsor/owner hygiene) if it is a busy production agent until Microsoft ships an automated migration path.
