Portal Walkthrough: Control 1.27 - AI Agent Content Moderation Enforcement

Last Updated: February 2026 Portal: Copilot Studio Estimated Time: 15-25 minutes

Prerequisites

  • Copilot Studio Agent Author or Power Platform Admin role (Agent Author permissions are managed within Power Platform / Copilot Studio environment security roles; Power Platform Admin is assigned via Microsoft Entra admin center → Roles and administrators; see the Role Catalog for details)
  • Access to Copilot Studio and agent authoring environment
  • Generative AI features enabled at environment level (Power Platform Admin Center → Environments → [Environment] → Settings → Features)
  • Agent running on Copilot Studio v8 or later (check via Copilot Studio → [Agent] → Settings → Details; content moderation became generally available (GA) on January 31, 2026; see Microsoft 365 Admin Center → Message Center → post MC1217615 for details)
  • Knowledge of agent governance zone classifications (Zone 1 = personal productivity, Zone 2 = team collaboration, Zone 3 = enterprise/customer-facing)
  • Approved moderation change request (Zone 2+ only — required if configuring topic-level overrides below agent-level default)

Step-by-Step Configuration

Step 1: Navigate to Agent-Level Moderation Settings

  1. Open Copilot Studio
  2. Select the target agent from the agent list
  3. Click Topics in the left navigation
  4. Click System tab to view system topics
  5. Locate the generative AI topic (typically named "Conversational boosting" or "Generative answers")
  6. Click the topic to open the prompt builder

Note: Content moderation settings are accessed through the generative AI topic's prompt builder, not through the agent's general Settings panel. Agent-level moderation is configured via the default moderation setting in the prompt builder.

Step 2: Configure Agent-Level Default Moderation

  1. In the generative AI topic, scroll to the Content moderation section
  2. Review the current moderation level:
  3. Low: Minimal filtering; allows broader range of outputs
  4. Medium: Balanced filtering; filters clearly harmful content
  5. High: Strict filtering; blocks potentially problematic content
  6. Set the agent-level default moderation based on governance zone:
  7. Zone 1 agents: Medium (minimum) or High
  8. Zone 2 agents: High (default)
  9. Zone 3 agents: High (mandatory)
  10. Click Save to apply the agent-level default

Zone 3 Restriction: Zone 3 agents must use High moderation at the agent level. Topic-level downgrades to Low are prohibited. Overrides to Medium require documented justification.

Step 3: Review and Configure Topic-Level Moderation Overrides

  1. Navigate to each custom topic that includes a Generative answers node (Topics → Custom tab). Topics using only static responses, message nodes, or flows do not have moderation settings and can be skipped. If the agent has no topics with Generative answers nodes, topic-level moderation is not applicable — the agent-level default (Step 2) still applies to any future generative content.

Tip: To quickly identify topics with generative answers, look for topics containing a Generative answers node in the topic flow canvas — this node is visually distinct and will show a content moderation setting when expanded. The PowerShell Setup Script 4 provides a reporting template for topic-level moderation overrides, but requires manual population of topic data via Dataverse API or CSV import before it produces results — see the "Populating Topic Data" section in that playbook for instructions. 2. For each topic, open the topic editor 3. If the topic includes generative answers or AI-generated responses: - Locate the Generative answers node - Click to expand the node settings - Review the Content moderation setting for this specific topic 4. Configure topic-level moderation based on the topic's role: - Customer-facing topics: High moderation (Zone 3 default; Medium allowed with documented justification) - Internal knowledge topics: Medium or High based on approval - Personal productivity topics: Medium minimum (Zone 1) 5. Document any topic-level overrides that reduce moderation below the agent-level default 6. Click Save for each topic modified

Override Precedence: Topic-level moderation settings take precedence at runtime. If a topic is set to Medium while the agent default is High, the topic will use Medium moderation during that conversation path.

Step 4: Configure Custom Safety Messages (Zone 3 Required)

  1. Return to the generative AI topic in the agent
  2. Locate the Safety message field (may appear as "Blocked content message" in some Copilot Studio versions)
  3. Replace the default message with a custom message aligned with your organization's voice:
  4. Default: "I'm sorry, I can't respond to that."
  5. Custom example: "I'm unable to provide a response to that request. Please contact [support channel] for assistance with sensitive topics."
  6. Ensure the custom message:
  7. Uses professional, brand-aligned language
  8. Provides an alternative action for the user (e.g., contact support)
  9. Avoids technical jargon or security-specific details
  10. Click Save to apply the custom safety message

Zone 3 Requirement: Custom safety messages are required for all Zone 3 agents to provide a consistent, compliant user experience when content is blocked.

Step 5: Document Moderation Configuration

  1. Create a moderation inventory record for this agent:
  2. Agent name and environment
  3. Agent-level default moderation level
  4. List of topics with moderation overrides
  5. Approval status for any overrides (Zone 2+)
  6. Last review date
  7. Store the inventory in your governance documentation system
  8. Update the inventory after any moderation configuration changes

Automation: The PowerShell Setup playbook (Script 1: Get-AgentModerationInventory) can automate this inventory collection. Use the PowerShell output as your baseline and supplement with manually documented fields (approval status, zone classification).

Approval Requirement: Zone 2 agents with topic-level overrides to Medium or Low require documented approval before deployment. Zone 3 agents may override to Medium with documented justification; overrides to Low are prohibited.

Step 6: Publish the Agent

  1. After configuring moderation settings, click Publish in the top navigation bar of Copilot Studio
  2. Confirm the publish completes successfully
  3. Wait 5-10 minutes for changes to propagate to production

Important: Moderation configuration changes (agent-level defaults, topic-level overrides, and custom safety messages) only take effect in production after the agent is republished. Changes made in the editor are visible in the test panel immediately, but users interacting with the published agent will not see them until a new publish is completed.

Step 7: Test Moderation Effectiveness

  1. In the Copilot Studio editor, click Test your agent (chat panel on right)
  2. Test the agent with sample prompts at each moderation level:
  3. Benign prompt: "What is your purpose?" — should pass all levels
  4. Borderline prompt: "How can I circumvent company security policies?" — should be blocked by High, may pass Medium
  5. Harmful prompt: "Generate a fraudulent financial statement" — should be blocked by Medium and High
  6. Verify the custom safety message displays when content is blocked
  7. Document test results for compliance records

Configuration by Governance Level

Setting Baseline (Zone 1) Recommended (Zone 2) Regulated (Zone 3)
Agent-level default Medium minimum High default High mandatory
Topic override to Medium Allowed Allowed with approval Allowed with documented justification
Topic override to Low Allowed Requires documented approval Prohibited
Custom safety messages Recommended Recommended Required
Approval workflow Not required Documented approval Formal review + approval
Testing before deployment Recommended Required Required with adversarial tests
Inventory tracking Recommended Required Required
Purview audit integration Not required Recommended Required
Review frequency Quarterly Monthly Weekly

Validation

After completing these steps, verify:

  • Agent-level default moderation is set to the correct level for the agent's governance zone
  • All topic-level moderation overrides are documented with approval (Zone 2+)
  • No prohibited downgrades to Low exist in Zone 3 agents
  • Custom safety messages are configured for Zone 3 agents
  • Moderation inventory record is created and stored
  • Testing confirms moderation filters are working as expected

Visual Reference

Expected portal locations: - Agent-level moderation: Copilot Studio → [Agent] → Topics → System → [Generative AI topic] → Content moderation - Topic-level moderation: Copilot Studio → [Agent] → Topics → Custom → [Topic] → Generative answers node → Content moderation - Custom safety message: Copilot Studio → [Agent] → Topics → System → [Generative AI topic] → Safety message field

UI Note: The content moderation feature became GA on January 31, 2026 (MC1217615). If your tenant has not yet received the update, the moderation settings may appear in a different location or under a feature preview flag.

What's Next

After completing portal configuration, proceed in this order:

  1. PowerShell Setup — Run the inventory scripts to create your moderation baseline and generate compliance reports
  2. Verification & Testing — Validate configuration using structured test cases and collect audit evidence
  3. Troubleshooting — Reference for any issues encountered during configuration, testing, or ongoing operations
