Microsoft Teams: View code blocks on mobile [MC1223820]

Message ID: MC1223820

[Introduction]

We’re introducing improved support for viewing code blocks in the Microsoft Teams mobile app for iOS and Android. This update responds to customer feedback from technical and developer-focused teams who rely on accurate, readable code formatting when collaborating on the go.

[When this will happen]

• Public Preview: We will begin rolling out in early February 2026 and expect to complete by mid-February 2026.
• General Availability (Worldwide): We will begin rolling out in mid-February 2026 and expect to complete by late February 2026.

[How this will affect your organization]

Who is affected: All users of the Microsoft Teams mobile app on iOS and Android.

What will happen:

• Users will be able to view code blocks sent from Teams desktop or web clients directly on mobile devices.
• Code blocks will appear as a message object (similar to a file preview) optimized for small screens:

   

• Tapping the preview will open a full-screen reader that includes:
  • Syntax highlighting
  • Line numbers
  • Scrollable containers for long snippets
• No admin controls are added with this update.
• This feature is enabled by default and requires no configuration.
• There is no impact to existing messaging workflows or policies.

[What you can do to prepare]

• No admin action is required. The feature will roll out automatically.
• Optional actions:
  • Notify developer or technical user groups who may benefit from this improvement.
  • Update internal documentation if you maintain guidance on using code blocks in Teams.
• Review Microsoft Teams documentation for more about code block formatting.

[Compliance considerations]

No compliance considerations identified. Review as appropriate for your organization.
