MC1470410 Microsoft Teams QR code protection for messages from external users

Summary

  • Microsoft Teams will automatically blur images containing QR codes when those messages come from external senders.
  • Users can reveal the image if they trust the sender and need to view or scan the QR code.
  • The change applies to organizations that allow external collaboration in Teams and will affect users on desktop, web, and mobile clients.
  • No admin configuration or policy changes are required, but admins should inform users and update help desk guidance.
  • Microsoft states the blurred state is a protection measure and does not mean Teams has identified the QR code as malicious.

Microsoft Teams will blur QR code images from external users by default starting October 2026 to reduce phishing risks. Users can choose to reveal these images if trusted. No admin action is needed, but user education on QR code safety is recommended. This applies across all Teams platforms.

Microsoft Message

Microsoft Teams is introducing additional protection for QR codes shared by external users in Teams messages. To help reduce the risk of phishing and fraud, images containing QR codes from external senders will be obscured by default. Users can choose to reveal the image before viewing or scanning the QR code.

This security enhancement promotes safer interactions with content received from external users while maintaining flexibility for trusted communications.

Rollout schedule

Targeted Release: Beginning in early October 2026 and expected to complete in early October 2026
