My Microsoft Teams Federation Notes

In this post I’ll describe how federation towards federated partners can work. I’ll not describe meetings and guest access for Teams which are great capabilities for modern teamwork across companies but not subject for this post. Teams provides options for federation with external organisations like suppliers, clients and partners.

Basically there are eight federation scenarios I’d like to describe below. The federation scenarios are based on Microsoft Teams as well as Skype for Business.

Skype for Business Federation

Let’s take a look on federation with Skype for Business. In Microsoft Skype for Business Server / Online (hereinafter: SFBx) there are two major federation types:

  • open federation: Users can communicate openly to everyone except users behind blocked domains.
  • closed federation: Users can communicate only to federated domains configured by the SFBx admin.

Teams Federation

Now, with Microsoft Teams federation is similair to SFBx federation but not 1:1 alike.

You can decide to federate with everyone, openly, except towards blocked domains (blacklist).

Or you can decide to federate only with allowed domains (whitelist).

Another thing to keep in mind is what’s your current Teams upgrade mode or status?

In Microsoft Docs there are five modes listed but not all are available by now.

  • Islands: All workloads on SFBx + Teams
  • Skype for Business-only: SFB for all workloads. Single client.
  • Teams-only: Teams for all workloads. Single client.
  • (not in Admin Center, Feb. 2019, TAP customers-only) Skype for Business with Teams (collaboration-only): SFB for chat, calling and meetings. Teams for collaboration.
  • (not in Admin Center, Feb. 2019, TAP customers-only) Skype for Business with Teams (collaboration and meetings-only): SFB for chat and calling, Teams for meetings and collaboration.

Scenario 1a+1b

You are on Microsoft Teams.

You can federate with other organisations having a) SFBx or b) Microsoft Teams, too.

Scenario 2a+2b

You are still on SFBx.

You can federate with other organisations having a) SFBx or b) Microsoft Teams, too.

Scenario 3a+3b

You are on SFBx as well as Microsoft Teams but your Teams Upgrade mode is “Islands”.

Your users are having two clients installed and only the SFBx works for federation communication.

You can federate only via SFBx with other organisations having a) SFBx or b) Microsoft Teams, too.

Scenario 3c+3d

You are on SFBx as well as Microsoft Teams but your Teams Upgrade mode is “Islands”.

Your users are having two clients installed and only the SFBx works for federation communication.

Your users cannot have an internal cross-client chat or else c) from SFB to Teams or d) from Teams to SFB.

Conclusion and summary

Teams federation provides the ability to federate with external organisations similair to what we’ve used to from SfBx. Nevertheless we need to pay attention to the user experience and federation experience which migh be slightly different during a coexistence of SFBx and Teams.
