Today I had to deliver a presentation in front of the French User Group of Exchange on the cool new capabilities of Exchange 2010 SP1!
As every IT Pro in the world, I started by downloading the SP1 beta from the following location: http://www.microsoft.com/downloads/details.aspx?FamilyID=a0965fc9-2723-4947-ae6b-74bc3808e72a&displaylang=en and started to look at the hidden gems from this release. The best place to start is the online documentation / help available here: http://technet.microsoft.com/en-us/library/ff459257(EXCHG.141).aspx
My demo environment is made of three virtual machines:
I turned off my VMs, and then took a snapshot for all of them and I was ready to go for the upgrade. In case something went wrong I had the opportunity to revert to my initial RTM settings. All went well for EX01 but EX02 was a little more complicated.
Here is the process you need to follow to perform the upgrade to Exchange 2010 SP1 UM:
If you do not perform this step (or if you do not install the Speech Server runtime), the MS Exchange Unified Messaging service will not start and errors similar to the following one will be logged in the event log:

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
