Data Loss Prevention for PHI in Email
A healthcare organization must comply with HIPAA. They need to automatically detect protected health information (PHI) such as medical record numbers in outgoing email, prevent users from sharing these emails with unauthorized external recipients, and apply a retention label that retains PHI emails for six years. Which Microsoft Purview solution should they use?
Quick Answer
This scenario bundles three requirements into one, and DLP is the answer because it's the Purview solution built to detect sensitive content and act on it in the same policy: identifying medical record numbers using a built-in or custom sensitive information type, blocking the message before it reaches an unauthorized external recipient, and — through an associated auto-labeling action — applying the retention label that keeps a copy for the required six years even after the block. The detection and the response happen together rather than as separate manual steps, which is what makes DLP suitable for a compliance requirement with a hard timing element like blocking a message in the moment it's sent. It's worth distinguishing this from Compliance Manager, which measures and scores compliance posture but doesn't inspect or act on individual messages, and from a standalone retention policy, which preserves content but has no detection or blocking capability of its own. Whenever a scenario asks for real-time detection of sensitive content combined with an enforcement action like blocking, DLP is the Purview solution doing the work, with retention layered on as a secondary action.
⚠ Common exam trap
A common mix-up: candidates confuse the detection and blocking capability of DLP with the classification-only capability of Information Protection (sensitivity labels), or they incorrectly think Data Lifecycle Management alone can enforce access controls, when in fact DLP is the only solution that combines content inspection, real-time blocking, and label application in a single policy.

Correct answer & explanation
✓
Microsoft Purview Data Loss Prevention (DLP)
Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it can automatically detect sensitive data like PHI (e.g., medical record numbers) in outgoing emails using built-in or custom sensitive info types, block unauthorized external sharing, and trigger a retention label action via auto-labeling policies to retain the emails for six years. DLP policies integrate with Exchange Online to inspect email content in transit, apply access restrictions, and enforce retention labels through Power Automate or auto-labeling rules.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Microsoft Purview Data Loss Prevention (DLP)
Why this is correct
DLP policies can be configured to scan Exchange Online emails for PHI, automatically block unauthorized sharing, and apply a retention label via an associated policy action. This meets all the stated requirements.
- ✗
Microsoft Purview Information Protection (sensitivity labels)
Why it's wrong here
Sensitivity labels can classify and protect data manually or via auto-labeling, but they do not natively block email sharing to external recipients. DLP is required for the enforcement action.
- ✗
Microsoft Purview Data Lifecycle Management (retention policies)
Why it's wrong here
Retention policies and labels manage how long data is kept and when it is deleted, but they do not detect sensitive content or prevent sharing.
- ✗
Microsoft Purview Audit
Why it's wrong here
Audit logging records events for investigation but does not provide real-time detection or enforcement against sharing PHI.

Variation 1. A healthcare organization must comply with HIPAA. They need to automatically detect protected health information (PHI) in emails sent from Exchange Online, prevent users from sharing these emails with unauthorized external recipients, and apply a retention label that retains PHI emails for six years. Which Microsoft Purview solution should they configure?
hard- ✓ A.Microsoft Purview Information Protection and Data Loss Prevention
- B.Microsoft Purview eDiscovery
- C.Microsoft Purview Communication Compliance
- D.Microsoft Purview Insider Risk Management
Why A: Microsoft Purview Information Protection and Data Loss Prevention (DLP) is the correct solution because it combines sensitive data classification (to detect PHI via built-in HIPAA data classifiers) with policy-based enforcement (to block sharing with unauthorized external recipients) and can automatically apply a retention label (via auto-labeling policies) to retain PHI emails for six years. This directly addresses all three requirements: detection, prevention, and retention.
