Microsoft Purview rollout: what to configure first.
Microsoft Purview does a great deal, which is exactly why so many deployments stall: teams try to switch everything on at once, drown in configuration, and ship nothing. After implementing Purview classification, labeling and DLP in federal, Crown and financial environments, we use one rule: deploy in the order that reduces real risk fastest.
First, classification. Turn on the built-in sensitive information types and trainable classifiers and let them run silently for two to four weeks. You are not enforcing anything yet; you are learning where personal, financial and legal data actually lives. Every decision after this is evidence-based instead of guessed.
Second, sensitivity labels on the narrow set of content that matters most. A simple three or four label taxonomy beats an elaborate one nobody applies. Auto-label where the classifiers are confident, and let people label where judgment is required.
Third, DLP in report-only mode against those labels, then graduate the policies that prove accurate to blocking mode. This sequence avoids the two classic failures: blocking legitimate work on day one, or running report-only forever. Retention policies come last, once the labeling foundation makes them meaningful.
The payoff for Canadian regulated organizations is direct: this is the control evidence PIPEDA, Quebec Law 25 and sector regulators expect, and it is the same foundation that makes Copilot safe to enable. Check where your deployment stands below.
