Microsoft Purview | Data Loss Prevention: Oversharing popups enhancements on Microsoft Outlook Win32
Microsoft is enhancing DLP features in Outlook Win32 for Microsoft 365 E5 Compliance users by introducing ‘Message contains’ and ‘Attachment contains’ predicates. These allow for client-side evaluation of email components and display relevant Policy tips and Oversharing popups. Rollout begins mid-April 2024 with completion by January 2025. No admin action is required for the update. Introducing two new Data Loss Prevention (DLP) Microsoft Exchange support predicates for DLP Policy tips and Oversharing popups features for Microsoft 365 E5 Compliance users: Message contains and Attachment contains. Unlike the broader Content contains DLP predicate that evaluated the entire email envelope, these new predicates are tailored for client-side evaluation of specific email components only (email body or attachments) and show DLP Policy tips and Oversharing popups accordingly in Microsoft Outlook Win32. This message is associated with Microsoft 365 Roadmap ID 376999 When this will happen: Public Preview: We will begin rolling out mid-April 2024 and expect to complete by late May 2024. Standard Release: We will begin rolling out late August 2024 and expect to complete by January 2025. How this will affect your organization: You can now create new DLP Policies or edit existing policies to include Policy tip and Oversharing popup features support for these new focused Message contains and Attachment contains predicates.
