However, if thunderbird meets *your* needs, by all means use it. It's
silly to use Outlook "just because it came with office."


I had found that tip already and deleted the file but still no joy.

I agree with your comment on not using Outlook, but as it comes as part
of a suit of software that I have paid for it would be nice to have it
working, as also at the moment I have other problems with Word,
Powerpoint, Publisher and Frontpage with the installer dialog popping up
each time I open them, so basically apart from Access and Excell most of
my office suit is unusable.

I have contacted MS regarding this and other problems with Vista, and
the general answer is use the KB's or the newsgroups.

It gets very frustrating when you can not get something as well known as
Office 2003 to actually work.
