Assessment Reasoning
The change introduces an automatic security feature in Teams that obscures QR code images from external senders. No configuration is required, but admins should inform users and update help desk guidance. The impact on admins is moderate due to communication and documentation updates. Users will see a change in message behaviour, but core workflows remain intact. Rollout is soon with defaults applied automatically, so planning and awareness are important.

📢 Official Microsoft Message Center Announcement

Microsoft Teams: QR code protection for messages from external users
Message ID: MC1470410

[What and why]

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
  • General Availability (Worldwide): Beginning in mid-October 2026 and expected to complete in mid-October 2026

What will happen

21837

  • Images containing QR codes sent by external users will be blurred by default in Teams messages.
  • Users can reveal the image if they trust the sender and want to view or scan the QR code.
  • The blurred image does not indicate that Microsoft Teams has determined the QR code to be malicious.
  • The protection is applied automatically to QR code images received from external senders.
  • No administrator configuration or policy changes are required.
  • The feature will be enabled by default as part of the rollout.

[Action required and recommendations]

We recommend that administrators:

  • Inform users that QR code images from external senders may appear blurred by default.
  • Remind users to verify the sender before revealing or scanning QR codes.
  • Review existing user education materials related to phishing awareness, QR code safety, and external collaboration.
  • Update internal help desk documentation to reflect the new user experience.
