Summary:
New predicates for email Data Loss Prevention in Microsoft Purview will allow organizations to set policies based on the number of recipients or domains in outgoing emails. This feature, rolling out in 2025, enhances data security and compliance. No admin action is required before the rollout. More details are available in Microsoft 365 Roadmap ID 483158.
Details:
Customers have expressed a significant pain point in managing and controlling the distribution of sensitive information in email. The lack of predicates to monitor the number of recipients or domains in outgoing emails poses a risk of data leaks and non-compliance with regulatory requirements. We are addressing this issue in Microsoft Purview | Data Loss Prevention by rolling out new predicates that will enable organizations to set precise policies that trigger alerts or actions when emails exceed a specified number of recipients or domains. This feature is essential for enhancing data security, ensuring compliance, and providing peace of mind to organizations concerned about unauthorized data dissemination.
This message is associated with Microsoft 365 Roadmap ID 483158.
