Setting up Federation in Skype for Business

Federation - Handshake

Skype for Business external connectivity (federation) enables a Skype for Business user to connect with users in other organizations that use Skype for Business as well as those that host their own Skype for Business Server on-premises.

Federated contacts can see presence, communicate by using IM, and make Skype-to-Skype audio and video calls.

There are a couple of federations important to have:

  • Skype for Business Online (Office365)
  • Exchange Online (Office365)
  • Skype for Consumer (Skype.com)

Following are the federation relationships that are supported by Skype for Business and the available modalities:

  • Skype for Business Server 2015   IM, Presence, Audio, Video, Conferencing
