After installing Microsoft Exchange Server 2010 onto a Windows Server 2012 R2, nothing was showing under the Exchange Management Console after expanding "Microsoft Exchange On-Premises".
Everything under "Exchange 2010 Organizational Health" was showing as "Unavailable"
When selecting the option to "Collect Organizational Health Data", the below error occurs stating "MMC has detected an error in a snap-in and will unload it"
To resolve this issue you need to install the latest Service Pack (SP3) for Microsoft Exchange Server 2010 - available from the following URL:
You can then install Update Rollup 14 for Microsoft Exchange Server 2010 SP3 from the following URL:
As you can see below, once SP3 has been installed, the Configuration options are now available/showing under "Microsoft Exchange On-Premises" after the updates are installed
