Dell supplied disk with "outlook 2002" and a confusing additional title "windows mobile 2003 second edition". It seemed to work ok, taking over the outlook express I had been using and really didn't want to leave.

Then changes happened - not by me - and the interface got simpler and it worked fine. THEN, Microsoft told me that security updates were available. Some of them I succeeded in downloading and installing, but some fail.

For the moment, the programs works. Any thoughts?

I have no idea what you are talking about. What disk? Supplied for what?

The X50v came with a disk containing Outlook 2002 and some additional software. As for the rest of that post - your guess is as good as mine.
