I tried deleting all those files, without success.

If I create a new profile, how do I import my previous pst into OL 2007?

I upgraded Outolook from 2003 to 2007.

After lauching Outlook, a little screen opens, showing that Outlook is
migrating accounts and archives. Suddenly Outlook closes down and an
error
message appears showing:

Not able to start Microsoft Office Outlook. Not able to open window of
Outlook. Not able to open this group of files. The attempt of starting
a
session in Microsoft Exchange has failed.

Should I reinstall the application?
