The WCF Tool (who can federate tool) is a free, end user or consultant tool to make users aware which of their own Outlook 2010 contacts are available to collaborate using Microsoft Lync or OCS.
The tool takes just a minute to install and run and the only requirement is that you have Outlook. That’s right, you don’t even need Lync or OCS, so this is a great sales tool for those who don’t even have a Microsoft UC solution yet as well as awareness driver for those who do. You likely will be surprised by some of your Outlook contacts that have Lync/OCS federation. (I was!)
The WCF Tool brings together the power of the Lync Federation Directory project list of Lync/OCS enabled organizations and DNS queries to discover which contacts in an Outlook contact list can collaborate.
