Microsoft adds new security, privacy, and compliance features to the Microsoft Teams chat and collaboration solution, including end-to-end encryption support for one-on-one voice calls.

Microsoft Teams is a cloud collaboration platform designed to allow an organization's team to stay organized and communicate via text, audio, and video, all in one place.

"End-to-end encryption (E2EE) for 1:1 Teams calls will be available to commercial customers in preview in the first half of this year," Microsoft said at Microsoft Ignite 2021.

"Teams will support end-to-end encryption for organizations to help customers meet their security and compliance requirements by providing an additional option for conducting sensitive online conversations."

Once the E2EE support for face-to-face ad hoc Teams VoIP calls rolls out, customers will be able to enable end-to-end encryption for 1:1 unscheduled calls if the information transmitted requires additional protection.

Teams admins will also be able to designate organization members who can use the new E2EE feature.

"Future updates will be made available to support customers' evolving compliance needs, including expanding to scheduled calls and online meetings," Microsoft added.
More information about these incoming Teams updates is available in this Microsoft 365 blog post.

Microsoft Teams calls are getting end-to-end encryption in July​

Microsoft Teams is getting better security and privacy next month with the addition of end-to-end encrypted 1:1 voice calls.

While Microsoft Teams already encrypts data at rest and in transit, it allows administrators to configure automatic recording and transcription of voice calls.

Due to this, Microsoft Teams calls are not suitable for sharing very sensitive information that should remain private between two individuals.

Starting in July, Microsoft Teams is getting end-to-end encryption for 1:1 VoIP calls so that their discussions remain entirely private.

"Teams will support an option to use end-to-end encryption (E2EE) for ad hoc 1:1 Teams VoIP calls, providing an additional option for conducting sensitive online conversations," Microsoft revealed today in the Microsoft 365 roadmap.

Microsoft has announced the public preview roll-out of end-to-end encryption (E2EE) support for one-to-one Microsoft Teams calls.

While Teams already encrypts data in transit and at rest, it also allows IT administrators to set up automatic recording and transcription of voice calls.

Because of this, Teams calls are not suitable when sharing sensitive info that should remain private between the two call participants.

Starting today, Microsoft Teams is getting end-to-end encryption for 1:1 calls which encrypts the real-time media flow (i.e., video and voice data) so that private one-to-one discussions remain entirely private, with no way for intermediate nodes or parties to decrypt them.

"We’re rolling out this preview of E2EE for unscheduled one-to-one calls today. When both parties in a one-to-one call turn on E2EE, the communication between those two parties in the call is encrypted from end-to-end. No other party, including Microsoft, has access to the decrypted conversation," said Mansoor Malik, Principal Group Product Manager for Microsoft Teams.

"With this release, only the real-time media flow, that is, video and voice data, for one-to-one Teams calls are end-to-end encrypted. Both parties must turn on this setting to enable end-to-end encryption."

Encryption for chat, file sharing, presence, and other content in the calls is also available for Microsoft 365 users (more info is available here).

I think this is the good including from Microsoft. Although, I still sometimes face issue in connection while using the Web version of Teams.
