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

Microsoft Teams is getting end-to-end encryption for 1:1 VoIP calls starting in July. Microsoft Teams already encrypts data at rest and in transit, but it allows administrators to configure automatic recording and transcription of voice calls. The feature will be a welcome addition as it allows the sharing of sensitive information without fear that they will be stored in recordings. In October 2020, Zoom also began supporting end to-end encrypted calls for meetings with up to 200 participants for both free and paid users.
