I installed MS Office Enterprise 2007 suite. All programs open and work
except Outlook 2007 - the one I need the most. It will open for about 15
seconds and then I get the message: "Not Respoding" then it stops and
closes.
I've run the Office Diagnostics and found no problems. I've reinstalled
the
entire suite - no luck either. I've run the 'repair' function from the
Setup
screen. That doesn't work either. What's up and how do I fix this?
