After you attach a Exchange 2010 Client Access role server to a Exchange 2007 environment you get an “An IIS directory entry couldn’t be created. The error message is Access is denied. HResult = -2147024891 It was running the command ‘Get-OwaVirtualDirectory’.” when you go to Server Configuration, Client Access in Exchange 2010 management console.

Get-OwaVirtualDirectory error

Solution: Because Exchange 2010 tries to read some information from the Exchange 2007 server, you have to add the “Exchange Trusted Subsystem” security group to the “local admin” group on all Exchange 2007 servers.
