Microsoft Teams | Customize live captions on mobile for improved accessibility [MC1146825]

Message ID: MC1146825

Introduction

Live captions in Microsoft Teams meetings are now available on mobile devices with enhanced customization options. Users can personalize captions by adjusting font color, background color, and caption height—making captions easier to read and follow, especially in varying lighting conditions or while on the go. This update aligns mobile capabilities with Teams on desktop and web, supporting a consistent experience across platforms.

This message is associated with Microsoft 365 Roadmap ID 499620.

When this will happen

• Targeted Release: We will begin rolling out in early September 2025 and expect to complete by mid-September 2025.
• General Availability (Worldwide, GCC): We will begin rolling out in mid-September 2025 and expect to complete by late September 2025.
• General Availability (GCC High): We will begin rolling out in early October 2025 and expect to complete by mid-October 2025.
• General Availability (DoD): We will begin rolling out in late October 2025 and expect to complete by early November 2025.

How this affects your organization

Teams’ mobile users will be able to customize live captions during meetings. These settings include:

• Font color
• Caption background color
• Caption height

Changes made on mobile will sync across Teams Desktop and Web, ensuring a consistent experience.

These settings are saved locally and persist across sessions, so users do not need to reconfigure them each time they join a meeting. Additionally, caption customization respects mobile OS accessibility preferences such as system font size and contrast settings, helping users maintain a consistent experience across apps.

Caption style settings are only available when captions are turned on during a meeting.

This feature is on by default and requires no admin action. Caption customization is managed at the user level, and existing caption policies will continue to apply across all platforms.
