Security News > 2021 > October > Better late than never: Microsoft rolls out a public preview of E2EE in Teams calls

Microsoft has finally kicked off the rollout of end-to-end-encryption in its Teams collaboration platform with a public preview of E2EE for one-to-one calls.

The company made the promise of E2EE for some one-to-one Teams calls at its virtual Ignite shindig in March this year and as 2021 nears its end appears to have delivered, in preview form at least.

The company's rival in the conference calling space, Zoom, added E2EE for all a year ago, making Microsoft rather late to the privacy party.

As for Microsoft's implementation in Teams, only real-time media flow for one-to-one calls can be encrypted and the feature must first be enabled by an administrator before users can turn it on.

Teams' Public Switched Telephone Network functionality does not support E2EE and chat in E2EE calls remains secured by Microsoft 365 encryption.

In the meantime, customers will just have to put their faith in Microsoft 365 encryption where E2EE is not an option.
