A fire department IT lead reviews Teams chats among crews for harassment and other policy risks. Which Microsoft Purview capability fits that communication-risk review?

Microsoft Purview Communication Compliance is the Purview capability built to detect, investigate, and remediate risky or inappropriate communications in Microsoft 365 workloads such as Teams. For a fire department IT lead reviewing crew chats for harassment and other policy risks, Communication Compliance matches the communication-risk review use case: it evaluates messages against policy, supports investigation workflows, and helps remediate violations without treating chat governance as an afterthought. Insider Risk Management correlates behavioral and contextual indicators to detect and investigate insider threat signals such as data theft or policy violations tied to user activity patterns in activities such as Teams, but it is not the capability built to detect and investigate the content of risky or inappropriate messages the way Communication Compliance is. Data Loss Prevention detects and investigates sensitive information sharing in messages such as Teams; it is not designed to flag harassment or other communication-conduct violations in chat content. Microsoft Purview eDiscovery searches and collects Teams chat content for legal investigations and case review workflows; it does not proactively detect and investigate risky or inappropriate messages like harassment the way Communication Compliance does. Exam caveat: AB-900 expects you to map Communication Compliance to risky or inappropriate communications—not to confuse it with eDiscovery search-and-collect for legal cases, AI app content filters, or cosmetic site settings. Operational check: confirm Communication Compliance policies cover the relevant Teams locations, that reviewers have appropriate investigator roles, and that findings drive documented remediation rather than informal screenshots alone.
