I decided to sharpen my skills on Exchange 2007 and Windows PowerShell.
So I got my 32-bit eval copy of Exchange 2007 and put it in on my virtualized test lab based on Microsoft Virtual Server 2005 R2. I built two machines, one a Windows Server 2003 domain controller running Exchange 2003 and another running Windows Server 2003 with Exchange Server 2007 (with Mailbox Server, Hub Transport Server, Client Access Server roles) joined to the same domain.
When I installed Exchange 2007, setup automatically placed Exchange 2007 in its own administrative group in the Exchange 2003 organization named “Exchange Administrative Group (FYDIBOHF23SPDLT)”.
Ever wondered what FYDIBOHF23SPDLT means?? Look at those letters again. If you replace each letter in FYDIBOHF23SPDLT with the previous letter in the alphabet, you get EXCHANGE12ROCKS. And boy, does it rock!!
