Federation and Public IM Connectivity

Office 365
 

Applies to: Office 365

Topic Last Modified: 2014-03-27

Lync external connectivity (federation) enables a Lync Online user to connect with users in other organizations that use Lync Online as well as those that host their own Lync Server on-premises. Federated contacts can see presence, communicate by using IM, and make Lync-to-Lync audio and video calls.

All federated communications are encrypted between the IM systems using access proxy servers. Microsoft does not control encryption after messages are passed to the federated partner’s network (if the partner is federated with an on-premises Lync Server or third-party network).

Lync external connectivity requires the consent and correct configuration of both parties of the federation relationship. After the federation is set up by the administrators of both sides, users in each company can see presence and communicate with users in the other company.

ImportantImportant:
The term “Lync federation” is specific to Lync and should not be confused with the requirements and capabilities of identity federation that are supported in Office 365.

Following are the federation relationships that are supported by Lync Online and the available modalities:

  • Lync Server 2013   IM, Presence, Audio, Video, Conferencing

  • Lync Server 2010   IM, Presence, Audio, Video, Conferencing

  • Office Communications Server 2007 R2   IM, Presence, Audio, Video, Conferencing

ImportantImportant:
  • Federated connections are not covered by the SLAs provided as a part of Office 365 subscriptions.

  • Federated connections are not offered in service availability targets.

  • Federated connections are excluded from the service continuity management Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO).

  • Text-based chat is the default communication type allowed across federated connections. Audio, video, and content sharing may be possible if the federated partner’s environment is correctly configured with Lync Server, which permits these types of communication.

  • File transfer is available with federated connections.

  • Lync Online supports only federation traffic routed through the Internet.

Customer Responsibilities
  • Provide necessary information, using the change management process, so that Microsoft can configure the federation.

  • Federation requires DNS configurations by the customer and each connected partner organization.

  • Partner organizations are solely responsible for correct configuration of their environments to support federation.

  • Direct the federated business partner to correctly configure the access edge and the audio and video edge.

Organizations can set up a hybrid Lync Server 2013 and Lync Online environment in which all users share the same domain, but some users are homed on-premises and some users are homed online. You can also configure hybrid deployments for integration with other Microsoft Office 365 applications, including Exchange Online and SharePoint Online. Hybrid deployments are discussed in detail in the Lync Server 2013 documentation at Lync Server 2013 Hybrid.
