Message Summary

Updated December 28, 2021: We have updated the rollout timeline below. Thank you for your patience.

End-to-end encryption is the encryption of information at its origin and decryption at its intended destination without the ability for intermediate nodes to decrypt. Teams will support an option to use end-to-end encryption (E2EE) for ad hoc 1:1 Teams VoIP calls. To support customer security and compliance requirements, IT will have full control of who can use E2EE in the organization.

This message is associated with Microsoft 365 Roadmap ID 70780

When this will happen:

We expect to begin rolling this out in early December (previously early November) and expect the rollout to be completed by early January (previously late December).

How this will affect your organization:

  • Admins:
    • A new policy will be added and it will have parameter to enable E2EE for 1-1 calls, default value is OFF so no impact until enabled. Admin can enable E2EE for a set of users or entire tenant.
  • End users:
    • If allowed by admin, the end user will see E2EE option in their settings, by default it will be OFF until switched ON by end user. E2EE calls will only support basic calling features like audio, video, screen share, chat and advanced features like call escalation, transfer, record, merge etc. will not be available.
