I have monitored various Exchange versions with SCOM previously with 2003 and 2007 and I am just now getting around to setting up Exchange 2010 monitoring in SCOM 2012. This is meant to be a gathering spot for all of the information I needed from various websites so that I can give credit to those who have figured out different pieces and also to give you a one-stop shop for the information. I will not go into overrides in this post. My setup consists of one Management Server, one Web Server/Data Warehouse, one Reporting Server, and the Database Server is SQL 2008 R2 clustered.
Exchange Server 2010 Management Pack Download – This is the first page I visited to download the installation guide and the management pack. Read through the management pack and setup accordingly before looking at the other articles below. This gives you 95% of the information that you need for your configuration.
Mailboxes on a database are Quarantined in an environment with System Center Operations Manager – As I am regularly on this site, I decided to search on the one issue with Qurantined mailboxes due to the MP. This has been resolved and provides information on overrides if you choose to use them.
Correlation Service Issue/RMS Emulator – I came across this site as I was searching for an error dealing with the Correlation Engine on the Management server. This posts gives you the information for tweaking the config file, the service account for the service and a way to grab the RMS Emulator name (This will usually be the management server name). Since this is an older management pack formatted for SCOM 2007 (and R2) it still looks for the RMS server which is no longer a role in SCOM 2012
Using these sites in addition to the deployment document allowed me to get up and running without any further issues.
