Lync-Skype connectivity

Enabling Lync and Skype to connect to one another, enterprise IT can continue to manage a unified communications infrastructure without constraining the reach of end users. 
Lync Server supports connectivity with Skype. This connectivity allows Skype users and Lync users to add each other as contacts, exchange instant messages and make audio calls. Skype connectivity allows your Lync Server users to add Skype contacts using the Skype user’s Microsoft Account (MSA). Skype clients can add Lync users to their contact list. Based on policies administratively set in Lync Server, Lync and Skype users will be able to communicate using instant messaging, see each other’s presence, and initiate audio calls.

What do Lync administrators need to do to get started?
1.       To connect their Lync users with the Skype community, Lync administrators first need to enable Lync-Skype connectivity. 
2.       For Lync Online, connectivity can be turned on from the Lync admin center within the Office 365 portal. 
3.       If you already have Windows Live Messenger federation working, no additional steps are necessary to enable Lync-Skype connectivity.
4.       If you have Office 365 Small Business Premium, sign in to Office 365, and go to Admin > Service Settings > Instant messaging, meetings and conferencing.  Turn on External communications.

What about end users?
Lync users can connect to Skype from Lync 2010 or Lync 2013, including any of the 2013 mobile clients.
1.       Skype users will need the latest Skype client available from
2.       Lync-Skype connectivity is supported from the Windows and Mac desktop clients with more options coming soon as other clients are updated.
3.       Skype users must sign in to Skype with a Microsoft account (formerly Windows Live ID) to communicate with Lync contacts

Configure federation and PIC
Federation is required to enable Skype users to communicate with Lync users in organization. Public Instant Messaging Connectivity (PIC) is a class of federation, and must also be configured to allow your Lync users to communicate with Skype users. Federation and PIC are configured using the Lync Server Control Panel, shown below.

Configure at least one policy to support federated user access
Using the Lync Server Control Panel, an administrator must configure one or more external user access policies to control whether Skype users can collaborate with internal Lync Server users.
