I frequently travel for a week or two at a time. At the office, I use a
desktop computer (XP w/Office 2007). When traveling I use a laptop (XP
w/Office 2003). I can easily upgrade the laptop to 2007, but I don't think
that solves my problem.

I want to be able to use all my Outlook files and Contacts from my desktop
on my laptop while traveling, updating my contacts as I travel, and then
update all that info on my desktop when I return.

What's the best way to do that?

What' I've been doing is copying the outlook.pst from my desktop on to a
thumb drive. The I copy that .pst file to the appropriate location on my
laptop, as working from the thumb drive is too slow. When returning to the
office, I reverse the process. Is that the best way of accomplishing my
objective, or is there something easier?

Thanks in advance,
Bob
