we are wireless away from home and can receive but not send through outlook.
This is a pain to have to go online to roadrunner and send a message!! Any
help for a novice is appreciated.
My guess is that your outgoing mail server (SMTP) is Roadrunner and,
as with most ISPs, it won't let you send mail through it when you're
not connected to their network, which you would not be if you're away
from home and using WiFi somewhere. You might check with Roadrunner to
see if they allow you to connect to the SMTP server in authenticated
mode, as some ISPs do to allow off-network use.
Some of the answers here seem like they might be useful:
