1 user, 2 computers

I have a laptop & a desktop. When I use each computer, my emails and other
info isn't "synced" and I tend to lose calendar items, contacts, and emails.
To make life simple, I'd like to use my Outlook & BCM data on both computers.
I tried to copy the pst & bcm files to a removeable drive ("thumb drive") so
that I can have the exact same info & current emails; but, it doesn't seem to
work. How can I accomplish this? Thanks in advance...
