Outlook Mobile: New external image handling option for safe senders

Outlook Mobile will add a new "Load images for safe senders" option for external images, aligning with Outlook for Windows and Mac. The rollout starts early April 2026. Existing settings remain unless changed, with no impact on security or compliance. No action is required unless updates are desired.

Introduction

To address customer feedback and align Outlook Mobile with other Outlook endpoints, we’re updating how Outlook for iOS and Android handles external images in email messages. This update introduces a new “Load images for safe senders” option. This change gives users and administrators more granular control over external image behavior while maintaining security and privacy protections.

When this will happen

We will begin rollout early April 2026 and expect to complete by late April 2026.
