On September 30, 2026, the Microsoft Purview Unified Classification Management Experience entered public preview. The new Classifiers experience gives administrators one place to discover, create, inspect, and manage classifiers across Microsoft Purview. To help administrators get started, here's a practical, self-contained playbook focused on operational value, safe change management, and repeatable classifier governance.

Microsoft Purview Unified Classification Management Experience

Feature overview and administrator playbook

Overview
The new Classifiers experience brings supported Microsoft Purview classification types into one place where administrators can discover, create, inspect, and manage classifiers. It adds practical visibility into classified-item counts and policy dependencies so administrators can make more informed, lower-risk changes.

Why this experience is important

Classification underpins data protection, data loss prevention, and data security. As classifier inventories grow, administrators need a consistent way to understand what exists, where it is used, and what could be affected by a change.

Centralized visibility Search and filter supported classifiers from a unified inventory instead of navigating separate management locations.	Safer change decisions Review classified-item counts and affected policies before editing or deleting a classifier.
Stronger governance Establish clear ownership, testing, approval, validation, and review expectations.	Better coverage analysis Use matched-item information and Data Explorer to understand where classifications occur and where gaps may exist.

What administrators can do

Discover supported classifier types and understand what the organization already uses.
Create classifiers from a single entry point with type-specific preparation guidance.
Review classified-item counts and inspect policies that depend on a classifier.
Validate matched items across supported data sources and investigate unexpected coverage.
Access Classifiers through Information Protection, Data Loss Prevention, or Data Security Posture Management, depending on tenant availability.

Supported classification capabilities include sensitive information types, named entities, Exact Data Match, trainable classifiers, credentials, document fingerprinting, optical character recognition, and on-demand classification.

How the experience can help

Reduce context switching: Use one inventory to find and inspect supported classifiers.
Understand impact earlier: Identify policy dependencies before a change reaches enforcement.
Improve accountability: Connect classifiers to business owners, policy owners, and reviewers.
Standardize operations: Apply the same lifecycle to routine maintenance, quality improvements, and retirement decisions.
