[dba-Tech] Excel 2007 question

A reader is trying to use some code I provided for linking Outlook and Excel 
with Excel 2007. She claims she has referenced the appropriate Excel 
library, but she gets a compile error right off with

Dim appExcel As Excel.Application.

Have that totally reworked the object model? I've used 2007 a bit, but only 
regular work -- no development work at all, so I haven't even begun to 
explore those kinds of changes.

I think she's linking from Outlook 2003 though -- would that matter?
