Microsoft Teams to Skype consumer interop – chat, calling and video

One of the features of Skype for Business is that Skype for Business users can communicate with Skype consumer users. I always saw this as a niche use case. The idea being a work user could contact there family, or maybe a supplier is using Skype consumer. Evidently, there was enough demand for the feature for Microsoft to bring it to Microsoft Teams.

It’s now rolling out to tenants and should be fully rolled out by end of April. Documentation here. The code is being rolled out to tenants at the moment.

Microsoft Teams and Skype consumer interop functionality

It offers the following functionality

  • Chat – Conversations are text-only. This means that there’s no rich formatting, @mentions, emojis, or other any of the other chat features that are available in a native Teams chat experience.
  • Calling – audio and video
  • It requires the Teams user to be in Teams Only mode (as federation only
    works in Teams Only mode)
  • It’s a single Microsoft Teams user to single Skype consumer
    user (P2) only, not meetings on either platform
  • Microsoft Teams users and Skype users can’t see each other’s presence.
  • Searching for Skype users by using their Skype ID or phone number isn’t supported, just email/Live ID
  • Works on desktop and mobile clients on both sides

How to enable Microsoft Teams and Skype consumer interop

You can enable the functionality in the Teams Admin Center (TAC)


You can also use PowerShell. Use the Set-CsExternalAccessPolicy cmdlet together with the EnablePublicCloudAccess parameter to control whether Teams users can communicate with Skype users. Setting the parameter to true allows Teams users to communicate with Skype users.

How a Teams user talks with a Skype consumer user

the Microsoft Teams user enters the Skype consumer users email into chat, click search externally.



Alternatively, the Skype consumer user can enter a Teams users email address. The Teams user is notified that they have a new message from a Skype user and have to first accept the message before they can reply to it.

  • If the Teams user selects Accept, the conversation is accepted, and both users can chat and call each other.
  • If the Teams user selects Block, the conversation is blocked, and subsequent messages and calls from that Skype user are blocked.
  • If the Teams user selects View messages, the message is displayed in Teams, which helps the user decide whether to accept or block the conversation.

You can then chat between the two


I also tested voice and video calling and they worked fine.
