I have a second e-mail account on which I can send from anywhere
(wireless laptop, Office 2003). However, I can only send on this
second account from a certain few locations and not others. At least
one other location at which I can receive uses the same provider that
I do at home (not able to receive at home). Could this be a firewall
configuration problem or could it have more to do with Outlook
settings? Suggestions for resolving this issue?

Either an authentication issue or a mismatch in the sending address domain
and the domain of the ISP.
