I was having the same problem. It appeared that none of my add-ins
were active yet when I checked HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft
\Office\Outlook\Addins the load value was either 2 or 3, I can't
remember. I changed all of these to "0" and haven't had the problem
since - Outlook 2007 flies and no error messages.

I imported the Pst from Outlook 2003 - XPpro Dell using Zone alarm 7 to my
new Dell Vista Business with full version of Office 2007 but being protected
by Norton Security Online: the import went well; but after 3 days the same
error was seen as described above - Scanpst repaired and has done
successfully for another 3 sessions: There's no obvious manual close down on
my part that would cause the issue ( don't use Windows defender or Off Comm)
so wonder like SM suggests whether the "online" virus checkers are checking
files whilst outlook is closing down?

Its pleasing to hear other users are having the same experience - over to
the Techs to resolve?
