Yesterday, the company announced that E2EE is now available to the general public.

An Additional Layer of Security

Microsoft first introduced end-to-end encryption (E2EE) support for Microsoft Teams calls back in October. 

As of Tuesday, once IT admins get the newest version of the video conferencing app, they will be able to enable and control the feature. To set policy for users, groups, or tenants they will need to use PowerShell. Users will need to turn the encryption on manually.

In the US and Europe, enterprise customers are beginning to use E2EE for Teams calls. The industries in which they work include professional services, manufacturing, telecommunications, and aerospace.

This end-to-end encryption, however, has one downside - while it is on, certain features of the web conferencing software won’t be available. For example, two people won’t be able to add a third one and make a group call. 

The other affected features are:

  • Recording
  • Live caption and transcription
  • Call transfer (blind, safe, and consult)
  • Call Merge
  • Cal Companion and transfer to another device
  • Call Park

If the two parties, participating in the conversation, need any of the listed options, they can turn the E2EE off from their settings.

Given the rising number of cyberattacks, however, it is best if the feature stays on. Experts even advise installing encryption software.
