Outlook: Additional formatting options in Outlook for iOS and Android

🚨 The Signal: Outlook for iOS/Android gains advanced formatting like font size and default font. This change increases the risk of users inadvertently sharing sensitive information due to inconsistent formatting, potentially bypassing data loss prevention (DLP) policies.

The Impact

All users are affected, with a low security risk of inconsistent data presentation and potential DLP bypass.

• End users: May inadvertently use inconsistent formatting, affecting professional communication.
• Security teams: Minor risk of DLP policies being less effective due to varied content presentation.
• Compliance teams: Potential for inconsistent data handling impacting information integrity.
• IT administrators: No direct impact, but may receive user queries regarding new features.

The Action

1. Review existing Microsoft Purview Data Loss Prevention (DLP) policies for Exchange Online to ensure they account for varied content formatting.
2. Communicate to end-users about the new formatting options and best practices for professional communication.
3. Monitor user feedback regarding the new formatting options and their impact on email content.
