While upgrading to Exchange 2010 SP2 using the GUI, you will come across the error message shown below. This only happens while upgrading the CAS role.

IIS 6 WMI Required for Exch 2010 SP2 Upgrade

The reason is that the CAS requires a new pre-requisite for supporting OWA mini (a new feature in SP2). Hence, either install it using Server Manager (right click “Web Server” and add role service) or Windows PowerShell.

IIS 6 WMI

To install using PowerShell, run Import-Module ServerManager followed by Add-WindowsFeature Web-WMI.

Install Web-WMI

Another option is to run the setup from the command line, Setup.Com /mode:upgrade /InstallWindowsComponents

Happy upgrading Winking smile
