Why This Guide Exists

Microsoft Purview is the most complex licensing area in the Microsoft portfolio. In 500+ EA engagements, fewer than 30% of organisations correctly identify which Purview features they have licensed, activated, and are paying for — but not using. This guide fixes that. It is written by advisers who have negotiated Purview compliance licensing at scale, without any commercial relationship with Microsoft.

Every data point, cost estimate, and negotiation tactic in this guide comes from live EA engagements. The guide is updated annually to reflect current pricing and product changes.
