Microsoft Teams Now Supports End-to-End Encryption

Posted on December 14, 2021 by Paul Thurrott in Microsoft 365 with 4 Comments

Microsoft announced today that Teams now supports end-to-end encryption, but only for one-to-one calls. And, yes, there are some further caveats too.

“Today, we are happy to announce that end-to-end encryption (E2EE) for Teams calls is now generally available,” Microsoft’s John Gruszczyk writes in the announcement post. “IT admins will have the option to enable and control the feature for their organization once the update has been received.”

E2EE will not be enabled by default, Microsoft says. Instead, IT has to configure the relevant policy and then enable it for whichever selected users. Then, those users will have to enable E2EE in their respective Teams clients.

Furthermore, several features will no longer be available when E2EE is enabled, including call recording, live captioning and transcription, call transferring, call parking, call merging, Call Companion and transferring to another device, and adding participants (which makes the one-to-one call a group call).

Finally, end-to-end encryption requires Teams for Windows or the Mac.

You can learn more about this feature from the Microsoft Tech Community website.

    Needs to allow all the features it doesn't and work in "Teams" calls.

    But it's a start I guess.

      Not to mention easier way to enable and require it on admin side instead of depending on the user.

    • VMax

      Some of those features require Microsoft to see call data, so it isn't possible to allow them with end-to-end encryption.

    I would just like to use Teams and my battery to instantly die and my fans crank to 1000. It doesn’t seem like to much to ask to use Teams on a laptop not plugged in just for a little while.
