After installing Dynamics CRM 4 on Windows Server 2008 R2 with SQL Server 2008 R2 & Exchange Server 2010 with all the latest updates etc, i cannot logon to Exchange Server 2010, get a message "Initialization failed, "ConsoleInitialize.ps1" is not recognized as the name of a cmdlet, function, script file or operable program".

I have had this problem before as well after i installed CRM 4 and the only solution i could find was to reinstall the whole Server 2008 R2, SQL Server 2008 R2 & Exchange Server 2010 and reinstall CRM but its the same story all over again and its making me crazy!

Please help me!
