Using a LAN connection with a dial-up option

[Terry]

I connect to my email provider through a LAN while in the
office, but want to be able to use my outlook from a dial-
up while traveling to connect to my email provider(not MSN
email). I have tried to use MSN dial-up to establish a
connection and then open Outlook. I am able to receive
mail but not able to send mail to my email provider. I
have checked the SMTP address and it is correct. I am not
sure why I cannot connect to my email server to send email
when I can connect and receive email.

Anyone have any thoughts?

Thanks,

Terry
