Dan, you are a steely-eyed, missile man! I was approaching 24 hours of being
into this problem (i.e. "Cannot open the Outlook Window"), when I found this
thread. I am running Outlook 2007/Vista 32/Ultimate/, and started getting
that message after a system hang yesterday. Like Cliff and others, I had
tried EVERYTHING to get this fixed, but nothing solved the problem, until I
found your post, Dan. So, as you suggested, I ran: "Outlook.exe
/resetnavpane" and it fixed my Outlook problem too! Thank you very much for
posting the problem (Cliff) and the solution (Dan).

Regards,
