Thank you, Hal.

Strangely, today, Outlook opened normally and finished the migration. I can
operate perfectly. The only difference between yesterday and today is that
now I am connected through my compay LAN.

Do you think this has anything to do with the Exchange account of my
company? Will this error happen every time a try to open Outlook not
connected to the LAN or was it only the first time?

Regards.

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?
