Microsoft announced two new offerings for Microsoft Office Communications Server, First, is Microsoft Office Communications Server 2007 R2 XMPP Gateway that allows basic presence sharing and instant messaging (IM) with Extensible Messaging and Presence Protocol networks Cisco Jabber and Google Talk.

Second, Microsoft also changed its public instant messaging connectivity (PIC) license requirements for Office Communications Server connectivity to the Windows Live and AOL public IM networks. Now, customers with OCS 2007 R2 Standard CAL (or equivalent Software Assurance rights) will no longer require an additional license to connect with the millions of people who use Windows Live and AOL for instant messaging and presence. This change took place in July for Windows Live, and is scheduled for AOL in October 2009.
