A healthcare organization must ensure that all outgoing emails containing protected health information (PHI) are automatically encrypted. External recipients must be able to read the encrypted messages without installing any software or signing up for a service. Which Microsoft Purview solution should be configured?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
Data Loss Prevention (DLP)
DLP can detect PHI and trigger encryption, but the actual encryption is performed by Message Encryption. The solution configured for encryption is Message Encryption.
Distractor review
Sensitivity labels
Sensitivity labels can be set to encrypt emails, but they require user intervention to apply, and the scenario requires automatic classification of PHI. Auto-labeling for emails is less straightforward than DLP.
Best answer
Microsoft Purview Message Encryption
Message Encryption provides the ability to encrypt emails and allow external recipients to read them securely. It integrates with DLP for automatic encryption.
Distractor review
Information protection policies
This is a broad category; the specific solution for email encryption is Message Encryption.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this MS-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Microsoft Purview Message Encryption — Microsoft Purview Message Encryption (formerly Office 365 Message Encryption) enables encrypted email that external recipients can read in a web portal without additional software. It can be triggered automatically by a Data Loss Prevention (DLP) policy that detects PHI. Sensitivity labels can also enforce encryption, but the automatic detection and email-specific encryption is best achieved by configuring Message Encryption via a DLP policy. The question asks for the solution being configured, which is Message Encryption.
