View the reports for data loss prevention
After you create your data loss prevention (DLP) policies, you'll want to verify that they're working as you intended and helping you to stay compliant. With the DLP reports in the Office 365 Security & Compliance Center, you can quickly view:
DLP policy matches This report shows the count of DLP policy matches over time. You can filter the report by date, location, policy, or action. You can use this report to:
Tune or refine your DLP policies as you run them in test mode. You can view the specific rule that matched the content.
Focus on specific time periods and understand the reasons for spikes and trends.
Discover business processes that violate your organization's DLP policies.
Understand any business impact of the DLP policies by seeing what actions are being applied to content.
Verify compliance with a specific DLP policy by showing any matches for that policy.

DLP incidents This report also shows policy matches over time, like the policy matches report. However, the policy matches report shows matches at a rule level; for example, if an email matched three different rules, the policy matches report shows three different line items. By contrast, the incidents report shows matches at an item level; for example, if an email matched three different rules, the incidents report shows a single line item for that piece of content.
Because the report counts are aggregated differently, the policy matches report is better for identifying matches with specific rules and fine tuning DLP policies. The incidents report is better for identifying specific pieces of content that are problematic for your DLP policies.
DLP false positives and overrides If your DLP policy allows users to override it or report a false positive, this report shows a count of such instances over time. You can filter the report by date, location, or policy. You can use this report to:
Tune or refine your DLP policies by seeing which policies incur a high number of false positives.
View the justifications submitted by users when they resolve a policy tip by overriding the policy.
Discover where DLP policies conflict with valid business processes by incurring a high number of user overrides.
All DLP reports can show data from the most recent four-month time period. The most recent data can take up to 24 hours to appear in the reports.
You can find these reports in the Security & Compliance Center > Reports > Dashboard.
View the justification submitted by a user for an override
If your DLP policy allows users to override it, you can use the false positive and override report to view the text submitted by users in the policy tip.
