The correct answer is to configure user-reported message settings in Microsoft Defender for Office 365. This works because when users report legitimate emails as false positives, the submissions feed directly into Microsoft’s automated machine learning and threat intelligence systems, which then adjust filtering policies to reduce future misclassifications without weakening overall security. On the MS-102 exam, this scenario tests your understanding of how to balance security controls with user feedback loops, often appearing as a trap where candidates mistakenly choose to disable phishing detection or lower thresholds. A common memory tip is “Report, don’t disable”—always prioritize user reporting mechanisms over turning off protections, because the goal is to train the system, not bypass it.

Correct answer & explanation
✓
Configure user-reported message settings in Microsoft Defender for Office 365
Option C is correct because configuring user-reported phishing settings allows users to report false positives, which feeds into Microsoft's machine learning and reduces future false positives. Option A is wrong because allowing all external emails bypasses security. Option B is wrong because disabling phishing detection removes protection. Option D is wrong because increasing spam confidence threshold may not address phishing false positives specifically.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. Your organization has Microsoft Defender for Office 365 Plan 2. You need to ensure that when a user reports a phishing email using the Report Message add-in, the email is automatically submitted to Microsoft for analysis and the user is notified of the result. What should you configure?
medium
A.Create a Safe Links policy to block the reported email
B.Configure an anti-phishing policy to automatically submit reported emails
C.Use a mail flow rule to send reported emails to a custom mailbox
✓ D.Configure a submission policy in the Microsoft 365 Defender portal
Why D: Option B is correct because a submission policy in the Microsoft 365 Defender portal defines the behavior for user-reported messages. Option A is wrong because anti-phishing policies handle detection, not user reporting. Option C is wrong because Safe Links policies protect links. Option D is wrong because mail flow rules handle routing, not user submissions.
