Microsoft announced today the general availability of end-to-end encryption support for one-to-one Microsoft Teams calls.
"Once IT has configured the policy and enabled it for selected users, those selected users will still need to turn on end-to-end encryption in their Teams settings. IT retains the ability to disable E2EE for one-to-one Teams calls as necessary."
While Teams already encrypted data in transit and at rest, the addition of E2EE support for calls also allows administrators to set up automatic recording and transcription of voice calls.
After enabling E2EE for calls in a tenant, Teams calls will be suitable for sharing sensitive info that should remain private between call participants.
When toggled on, the real-time media flow in Microsoft Teams 1:1 calls will also be encrypted for head-to-head discussions to remain entirely private, with no way for other parties to decrypt them.
Encryption for Teams calls is also available for Microsoft 365 customers.
