| description | Implement a phishing report button (Microsoft 365 built-in Report button or third-party like KnowBe4/Cofense) in email clients with a SOAR-driven automated triage workflow that classifies reported emails, extracts IOCs, takes remediation actions, and gives feedback to reporters. Use when deploying user-reported phishing intake or automating triage of the resulting reporting mailbox. |

Building Phishing Reporting Button Workflow
Overview
A phishing reporting button empowers users to flag suspicious emails directly from their email client, creating a critical feedback loop between end users and the security operations center. 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.
When to Use
- When deploying or configuring building phishing reporting button workflow capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Microsoft 365 or Google Workspace with administrative access
- SOAR platform or automation capability (Microsoft Sentinel, Splunk SOAR, Cortex XSOAR)
- Dedicated reporting mailbox for phishing submissions
- Email security gateway with message retraction capability
- Security awareness training platform for feedback loop
Workflow
Step 1: Deploy Phishing Report Button
- Enable Microsoft built-in Report button via Security & Compliance Center
- Configure user reported settings: route to reporting mailbox and Microsoft
- For third-party: deploy KnowBe4 Phish Alert Button or Cofense Reporter
- Verify button appears in Outlook desktop, web, and mobile clients
- Configure report options: Report Phishing, Report Junk, Report Not Junk
Step 2: Build Automated Triage Pipeline
- Configure reporting mailbox monitored by SOAR platform
- Auto-extract IOCs from reported emails: URLs, attachments, sender info, headers
- Submit URLs to VirusTotal, URLScan.io for reputation check
- Submit attachments to sandbox for dynamic analysis
- Check sender against known threat intelligence feeds
- Auto-classify: confirmed phishing, spam, simulation, legitimate
Step 3: Implement Response Actions
- Confirmed phishing: auto-retract from all inboxes, block sender domain
- Confirmed spam: move to junk for all recipients
- Simulation email: mark as correctly reported, credit user
- Legitimate email: return to inbox, notify reporter
- Generate IOC report for threat intelligence team
