Anyone taken Exam 77-604: MOS: Using Microsoft Office Outlook 2007?

My boss at work wanted me to get this ceritification, so we can upgrade to everyone using outlook 2007 (I know, I know.)

Anyhow, I was wondering if anyone took this test and what material they used to study? How was the test?

Just curious, I am fairly good with setting up and using 2003 and 2007, but I know there is something on the test that I will need to know that I am sure I am missing..
