[Outlook Mac] Purview DLP Wait-on-Send Support

🚨 The Signal: Outlook for Mac now supports Purview DLP 'wait-on-send' policies, forcing email inspection before sending. This enhances data loss prevention by ensuring sensitive information is evaluated against policies, giving security teams more control over data egress.

The Impact

Security teams and end-users are affected, reducing the risk of sensitive data exfiltration.

• Security Teams: Enhanced control over sensitive data egress.
• End-users: Potential delays in sending emails due to policy evaluation.
• Compliance Officers: Improved enforcement of data protection policies.
• Admins: New configuration options for DLP policies.

The Action

1. Review existing Microsoft Purview Data Loss Prevention policies in the Microsoft Purview compliance portal.
2. Identify policies where 'wait-on-send' enforcement is appropriate for Outlook for Mac.
3. Enable and configure the desired maximum wait period within the relevant DLP policies.
4. Communicate potential email sending delays to end-users.
