You can't share Outlook or OE files across two PCs without a third party
software solution. The problem is that you can't access the database from
the second computer once it's open on the first one (and vice versa).
Exporting the entire file will of course work, but that seems to defeat the
purpose since you'd have to go to both computers to make this work. While
Remote Desktop will work, that's a pretty extreme way to go about what she
wants to do. I'd suggest you look into a thrid party sharing program
(Frankly, I'm not sure they exist for OE but I used one for a while with
Outlook and it did the trick). Eventually, I just got separate email
addresses as that was a MUCH simpler solution. You can always then forward
the one email address to the other if you want to get all your mail on one
PC - but I don't think you can forward both back and forth to each other so
I don't think forwarding would really solve the sharing problem.
Again, the answer to your problem is a third party softward program that
shares .PST files (for Outlook and whatever it it for OE). Check
www.download.com or
www.tucows.com for something.
