About this tag
Purview labels are Microsoft's sensitivity labels used to classify and protect data in Microsoft 365. Recent discussions on WindowsForum highlight a significant privacy flaw (CW1226324) where Microsoft 365 Copilot Chat bypassed Purview sensitivity labels and Data Loss Prevention (DLP) controls, reading and summarizing emails marked as Confidential. This bug exposed a gap in enterprise data governance, as Copilot accessed labeled emails from Sent Items and Drafts despite configured protections. The issue was patched with a server-side update, but it underscores the need for careful governance of AI features within Microsoft 365. Topics include data classification, DLP, and AI compliance.
