My experiences with Microsoft UC and Exchange with some other stuff
The Lync Server 2010 Best Practices Analyzer (BPA) has just released and can be downloaded here. The Lync BPA is only designed to scan Lync components and not OCS components. You will need to use the OCS BPA if you need to scan OCS infrastructure.
Why it is not integrated in the product like in Exchange?
With OCS and now Lync, it has always been a seperate product. This is just how the product team decided to go with it.
