(Updated) Microsoft Outlook for iOS/Android: Improved Contacts with profile enrichment and duplicate management

🚨 The Signal: Outlook Mobile will automatically enrich contacts with directory data and hide duplicates. This streamlines contact views but exposes more internal organizational data on mobile devices by default, with no admin controls.

The Impact

All mobile Outlook users are affected, with a low security risk of increased internal data exposure on potentially less secure endpoints.

• End Users: See more internal directory details on mobile devices.
• Security Team: Increased data exposure on mobile endpoints by default.
• Admins: No controls to restrict this data enrichment.
• Compliance Teams: Potential minor impact on data minimisation policies.

The Action

1. Review existing mobile device security policies for data handling.
2. Communicate to users about the enhanced contact information display.
3. Monitor for any user feedback regarding data visibility on mobile.
