juste released Understanding and Troubleshooting Microsoft Exchange Server Integration white paper, wrote by Dave Howe (email@example.com)
From the paper:
"The purpose of this document is to introduce the reader to some of the new client features that are available whenever Microsoft® Lync™ Server 2010 communications software is integrated with Microsoft® Exchange Server 2010. Successfully integrating these two enterprise communications solutions can be challenging, especially considering that there are subtle differences in the way that services from each product are leveraged by Lync Server 2010 clients.
I decided to write this document after troubleshooting several Exchange Server 2010 integration issues reported by Technology Adoption Program (TAP) customers during the Microsoft Lync Server 2010 Beta program. The information contained in this document is not intended to be authoritative with regard to this topic. Rather, this document can simply be described as a collection of information that I’ve read from various product specifications as well as some general troubleshooting information. That’s all – nothing more.
Please note that this document does not cover Microsoft® Lync™ 2010 instant messaging (IM) and Microsoft Exchange Outlook Web Access (OWA) integration. For details, see the following:
