Federation is an important goal for the Office Communications Server team and we are excited to announce several changes to public IM federation between Office Communications Server and public IM networks, effective July 1, 2009:

· The Live Communications Sever Public IM Connectivity (LCS PIC) license will be renamed Office Communications Server Public IM Connectivity (OCS PIC) license.

· Customers with Office Communications Server 2007 R2 Standard CAL or Office Communications Server 2007/Live Communications Server 2005 SP1 Standard CAL with Software Assurance will no longer require an additional license to federate with Windows Live.  (A license will still be required for federation with AOL & Yahoo!.)

· With Windows Live federation, customers are able to add Windows Live contacts to their Office Communicator contact list, view presence and send and receive instant messages.

We will continue to work with our partners to enable more options that allow you to communicate seamlessly with customers, partners, friends and family on different networks.

Update July 6, 2010 - In the time since this blog was posted, the content in the link above has been updated to reflect changes for AOL licensing as well.
