Microsoft Teams brings end-to-end encryption to one-on-one calls

Microsoft today announced that its video conferencing app, Microsoft Teams, is getting support for end-to-end encryption. The company had first announced this feature back in March this. Then in October, it started public testing this feature. Now, almost two months later, the company has finally rolled out end-to-end encryption for one-on-one calls in Microsoft Teams. End-to-end encrypted calls for Teams is available on the latest version of the Teams desktop client for Windows or Mac.

“Multiple enterprise customers in the US and Europe across industries such as aerospace, manufacturing, telecommunications, and professional services are in the process of rolling out E2EE for Teams calls,” Microsoft wrote in a blog post.

The company clarified that end-to-end encryption will not be enabled by default for one-on-one Teams calls. Instead, it will have to be enabled by IT admins. “IT admins will have the option to enable and control the feature for their organisation once the update has been received,” the company added in the post.

Microsoft also clarified that end-to-end encryption will not be available to all users within an organisation by default. The company said that once IT has configured the policy and enabled it for selected users, those selected users will still need to turn on end-to-end encryption in their Teams settings. This means that enabling end-to-end encryption is a two-step process. First, the IT team of an organisation will have to enable this feature for select users and then those users will have to turn on this feature with the Teams settings to secure their calls.

In addition to this, Microsoft said that some features will be unavailable when users have enabled end-to-end encryption for Teams one-to-one calls. The list includes call recording, live caption and transcription, call transfer, call park, call merge, call companion and transfer to another device and the ability to add a participant to turn the one-to-one call into a group call. Users who want to use any of these features while making one-on-one calls will have to disable the end-to-end encryption functionality on Microsoft Teams to use these features.
