Planning for public instant messaging connectivity in Lync Server 2013
Topic Last Modified: 2013-10-07
Public Instant Messaging Connectivity is a class of federation, and is configured to allow your internal and external Lync Server 2013 users to add contacts from any of the following:
America Online (AOL) contacts
This class of federation requires the following planning considerations:
Windows Live Messenger users can have peer-to-peer audio/visual communication with Lync Server 2013 users, in addition to instant messaging. Your Edge Servers must meet specific port and protocol requirements. For details, see Determine external A/V firewall and port requirements for Lync Server 2013.
Yahoo instant messaging has no unique requirements, other than those typically used in the planning and deployment of the typical Edge Server that is providing federation.
America Online requires that your Edge Server certificate assigned to the Access Edge service has a client enhanced key usage (EKU).
