End-to-end encryption (E2EE) functionality for Microsoft Teams is now available. Microsoft Teams is adding E2EE security support for all one-to-one conversations after introducing the functionality earlier this year and running a public preview since October. Today, all Teams users will receive an update that will allow IT administrators to activate and regulate E2EE for one-on-one conversations.
“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,” says John Gruszczyk, a Microsoft technical product manager.
Currently, Microsoft Teams encrypts data in transit and at rest, allowing authorized services to decode information for data retention record needs. Microsoft also employs SharePoint encryption to protect at-rest files and OneNote encryption to protect notes stored in Microsoft Teams. In Teams, all conversation material is encrypted both in transit and at rest.
This new E2EE encryption will improve the security of one-on-one communications within Teams, but it will disable some Teams capabilities if IT administrators enable it. In one-to-one calls that employ E2EE, recording, live captioning / transcription, call transfer, call park, call merging, and functions like transferring calls to another device or adding participants to make a group call will all be blocked.
