Microsoft's built-in Report button is now the recommended approach, replacing the deprecated Report Message and Report Phishing add-ins. When combined with automated triage using SOAR platforms, reported emails can be classified, IOCs extracted, and remediation actions taken within minutes. Organizations with effective phishing reporting programs see 70%+ report rates in phishing simulations.\n\n\n## When to Use\n\n- When deploying or configuring building phishing reporting button workflow capabilities in your environment\n- When establishing security controls aligned to compliance requirements\n- When building or improving security architecture for this domain\n- When conducting security assessments that require this implementation\n\n## Prerequisites\n- Microsoft 365 or Google Workspace with administrative access\n- SOAR platform or automation capability (Microsoft Sentinel, Splunk SOAR, Cortex XSOAR)\n- Dedicated reporting mailbox for phishing submissions\n- Email security gateway with message retraction capability\n- Security awareness training platform for feedback loop\n\n## Workflow\n\n### Step 1: Deploy Phishing Report Button\n- Enable Microsoft built-in Report button via Security & Compliance Center\n- Configure user reported settings: route to reporting mailbox and Microsoft\n- For third-party: deploy KnowBe4 Phish Alert Button or Cofense Reporter\n- Verify button appears in Outlook desktop, web, and mobile clients\n- Configure report options: Report Phishing, Report Junk, Report Not Junk\n\n### Step 2: Build Automated Triage Pipeline\n- Configure reporting mailbox monitored by SOAR platform\n- Auto-extract IOCs from reported emails: URLs, attachments, sender info, headers\n- Submit URLs to VirusTotal, URLScan.io for reputation check\n- Submit attachments to sandbox for dynamic analysis\n- Check sender against known threat intelligence feeds\n- Auto-classify: confirmed phishing, spam, simulation, legitimate\n\n### Step 3: Implement Response Actions\n- Confirmed phishing: auto-retract from all inboxes, block sender domain\n- Confirmed spam: move to junk for all recipients\n- Simulation email: mark as correctly reported, credit user\n- Legitimate email: return to inbox, notify reporter\n- Generate IOC report for threat intelligence team\n\n### Step 4: Create Feedback Loop\n- Send automated thank-you response to reporter within 5 minutes\n- Include classification result when analysis completes\n- Track reporter accuracy and engagement metrics\n- Recognize top reporters in monthly security newsletter\n- Feed reporting metrics into security awareness training program\n\n### Step 5: Measure and Optimize\n- Track mean time to triage (target: under 10 minutes automated)\n- Monitor report volume trends and false positive rates\n- Measure user reporting rate in phishing simulations\n- Report on confirmed threats caught by user reports vs. gateway\n- Optimize automation rules based on classification accuracy\n\n## Tools & Resources\n- **Microsoft Report Button**: Built-in Outlook phishing reporting\n- **Cofense Reporter + Triage**: Enterprise phishing reporting and automated analysis\n- **KnowBe4 Phish Alert Button**: Integrated reporting with simulation platform\n- **Microsoft Sentinel**: SOAR automation for triage workflow\n- **Proofpoint CLEAR**: Closed-loop email analysis and response\n\n## Validation\n- Report button visible and functional across all Outlook platforms\n- Reported email arrives in dedicated mailbox within 60 seconds\n- Automated triage classifies test phishing email correctly\n- Auto-retraction removes confirmed phishing from all inboxes\n- Reporter receives feedback notification with classification\n- Metrics dashboard shows report volume and accuracy trends\n\n## Other files in this skill\n\n-
