What you need to know

  • Microsoft Teams will soon support end-to-end encryption for one-to-one voice calls.
  • The feature was initially announced in March 2021, and could arrive as early as next month.
  • End-to-end encryption helps secure calls but restricts certain features, such as call recording.

Microsoft Teams users will soon be able to use end-to-end encryption for ad hoc one-to-one calls. The feature will improve the security of calls made through Teams, allowing people to use the service for more sensitive data. Microsoft initially announced the feature back in March (via MSPU), and it could arrive as early as next month, according to the Microsoft 365 roadmap.

IT admins will be able to control which people within an organization can use end-to-end encryption for calls, including limiting the feature to a subset of people or rolling it out across an entire organization.

Here's the full description of the feature from the Microsoft 365 roadmap:

Teams will support an option to use end-to-end encryption (E2EE) for ad hoc 1:1 Teams VoIP calls, providing an additional option for conducting sensitive online conversations. To support customer security and compliance requirements, IT will have full control of who can use E2EE in the organization.

In the column for products, the Microsoft 365 roadmap lists Android, iOS, and Desktop, so it's safe to say that the feature will work across all versions of Teams when it rolls out.

When using end-to-end encryption for calls, certain features will be restricted, including recording calls and transcription.
