Well good news i’ll say, because before it happen you can use separately all the Microsoft products, Lync offer an integrated environment:
* Get easy access to presence, instant messaging, voice, and audio, video, and Web conferencing—all from the new Microsoft Lync 2010 client.
* Use one set of contacts across Lync 2010 and Office applications.
* Communicate with context from within the applications you use most, including Microsoft Outlook and Microsoft SharePoint.
* Deliver access to presence, instant messaging, and other capabilities for workers on the go via PCs, browsers, and mobile phones.
