You're welcome, I'm glad your problem got solved.
If you're still using Entourage for your email, that same folder can be individually backed up as needed. I back up that folder to a jump drive when I'm on the road with just the laptop. I can then easily transfer it onto the office desktop computer when I get back and voila... all my emails, including all the ones I sent
from my laptop, are synced on my main office computer.
