In that case you might need to request an elevation of privileges in your
code before you try to create the application object. That I have no idea
about, you might want to check in a Vista development forum on how to do
that.

Hi Ken,

I found the time to do some more tests: The problem is not an AddIn, it's
the user access control of Vista! I can disable all AddIns, but it still
doesn't work with UAC enabled. I can enable all AddIns, but disable UAC,
and
it works.

Is this ment "by design", which means: There is no way to connect to
Outlook
with UAC enabled?
