In March 2025, the New South Wales (NSW) Department of Education discovered that Microsoft Teams had begun collecting students' voice and facial biometric data without their prior knowledge. This occurred after Microsoft enabled a Teams feature called 'voice and face enrollment' by default, which creates biometric profiles to enhance meeting experiences and transcriptions via its CoPilot AI tool.

The NSW department learned of the data collection a month after it began and promptly disabled the feature and deleted the data within 24 hours. However, the department did not disclose how many individuals were affected or whether they were notified. Despite Microsoft's policy of retaining data only while the user is enrolled and deleting it within 90 days of account deletion, privacy experts have raised serious concerns. Rys Farthing of Reset Tech Australia criticized the unnecessary collection of children's data, warning of the long-term risks and calling for stronger protections.
