did the copy of Office you installed from actually have Outlook 2007?
Outlook 2007 isn't shipped in all Office 2007 packages.

I upgraded from Office 2003 professional to Office 2007 standard. After
installation everytime I do a software update I get updates for Outlook
2003.
I also get the message that an extension failed to initialize. Cannot open
file: extend.dat.
