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

🚨 The Signal: Outlook Mobile 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, improving compliance and control over data egress.

The Impact

Security teams and Purview admins are affected by enhanced data exfiltration prevention capabilities.

• Security Teams: Reduced risk of sensitive data exfiltration via mobile email.
• Purview Admins: New configuration options for DLP policies on mobile.
• End Users: Potential delays in sending emails from Outlook Mobile due to policy evaluation.

The Action

1. Review existing Microsoft Purview Data Loss Prevention policies for mobile.
2. Determine if 'wait-on-send' enforcement is appropriate for your organisation's risk profile.
3. Enable and configure the desired wait period within relevant DLP policies via the Microsoft Purview compliance portal.
