In addition to the support that previous Lync Server releases have provided for integration with on-premises deployments of Exchange Unified Messaging (UM), Lync Server 2010 introduces support for integration with hosted Exchange UM. Hosted Exchange UM enables Lync Server to provide voice messaging to your users if you transfer some or all of them to a hosted Exchange service provider such as Microsoft Exchange Online.

Lync Server Enterprise Voice uses the Exchange UM infrastructure to provide call answering, call notification, voice access (including voice mail), and auto attendant services. For details, see Features of Integrated Unified Messaging and Lync Server 2010.
