Microsoft Purview Data Explorer
A Purview data classification tool that shows a current snapshot of items carrying a sensitivity label, a retention label, or a detected sensitive information type, and lets authorized admins view those items.
Microsoft Purview Data Explorer is a read-only view in the Microsoft Purview portal (under Information Protection) that shows a current snapshot of items carrying a sensitivity label, a retention label, or a detected sensitive information type across Microsoft 365 data such as SharePoint, OneDrive, and Exchange. Admins use it to understand where sensitive content resides before deploying Copilot, so data is protected before AI can surface it. The key exam contrast is with Activity Explorer: Data Explorer answers where labeled items reside, while Activity Explorer reports what actions users took on them. Access is tightly scoped through the Data Explorer List viewer role, with the Content viewer role additionally permitting reading actual item contents.
