SC-900 Communication Compliance policy Practice Question
A company is implementing Microsoft Purview Communication Compliance to detect inappropriate messages. They need to monitor Microsoft Teams channel messages and chat messages for potential policy violations. Which configuration is required?
⚠ Common exam trap
SC-900 often tests whether candidates confuse DLP (protect sensitive data) with Communication Compliance (detect inappropriate communications); picking DLP for a harassment-detection scenario is the classic wrong answer.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a Communication Compliance policy that includes Teams messages as the supervised communication channel.
Communication Compliance in Microsoft Purview is configured by creating a policy that specifies the supervised communication channels, and Microsoft Teams chats and channel messages are selectable channels within that policy. Enabling Teams as a supervised channel is the required configuration to detect inappropriate messages in Teams. DLP, retention, and third-party archiving address different compliance goals.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Microsoft Purview Data Loss Prevention (DLP) policies for Teams.
Why it's wrong here
DLP policies detect and block sensitive information such as credit card or personal data, not inappropriate language or harassment. It is tempting because DLP also monitors Teams messages, and would be correct if the requirement were preventing sharing of sensitive data rather than detecting offensive or policy-violating communications.
- ✗
Set up an Exchange Online retention policy to retain Teams messages.
Why it's wrong here
Retention policies only preserve messages for eDiscovery and do not evaluate content against communication compliance policy conditions. It is tempting because Teams message retention is a prerequisite for some compliance workloads, and would be correct if the goal were preserving Teams chat and channel data rather than detecting inappropriate content.
- ✗
Deploy a third-party archiving solution for Teams messages.
Why it's wrong here
A third-party archiving tool stores Teams messages externally but cannot apply Microsoft Purview Communication Compliance classifiers or review workflows. It is tempting because archiving captures the same Teams chat and channel content, and would be correct if the requirement were long-term retention or journaling rather than in-product policy violation detection.
- ✓
Configure a Communication Compliance policy that includes Teams messages as the supervised communication channel.
Why this is correct
Communication Compliance policies define supervised communication channels, and Microsoft Teams chat and channel messages must be selected as a supervised channel for those messages to be scanned. Without adding Teams, the policy only covers Exchange email and other configured sources.
