End-to-end encryption (E2EE) is a security feature that users covet on communication services, especially those focused on enterprise and business. Microsoft Teams so far has not used E2EE for one-to-one calls, but that is now changing. According to Microsoft, it has finished testing end-to-end encryption for one-on-one calls and it is now rolling out to Teams.

However, while that is good news, there is also some bad news. Specifically, for some reason enabling E2EE in Microsoft Teams results in some features not working properly. In other words, you will need to decide whether you prefer privacy or a fully functioning Teams experience.

End-to-end encryption is valuable because it essentially locks data while it is in transit, preventing third parties from accessing it. This is important for one-on-one calls because it means no-one (cybercriminals, advertisers, or even Microsoft) can listen in.


It is worth noting Microsoft Teams already uses E2EE on regular data such as messages, calendar, information, and other features. Only one-to-one calls were left out.


Although, Microsoft says the caveats for using the feature are broad. For example, enabling E2EE for calls means that other in-call features do not function, such as call transfers, live captions, group calls, and recording.

In other words, if you want to have the privacy of end-to-end encryption, you must go back to a bare bones call feature set. However, there is a toggle for turning off E2EE. So, if you know you will need any of those features you can compromise your privacy and disable the feature.

It is also worth noting E2EE is disabled by default, so if you want to use it you will have to enable it in the options.

Tip of the day: Whether it’s for a presentation, song, or YouTube video, at some point in your life you’ll need to record audio from your computer. Windows 11 has multiple options to record sound due to its litany of apps. In our tutorial, we show you how to record audio using the built-in Windows 10 Voice Recorder and the freeware audio editor Audacity.
