You need to contact your ISP. Very many will not allow you to use their
SMTP server unless you are connected to them. Some, however, allow you to
authenticate first with your username and password and then the send is
allowed. You need to check with them to determine what you can do.

If they allow authentication, then you need to check the option under Tools
| Accounts | Mail | Properties | Servers

Hi,

My outlook is correctly configured to send email via my smtp server. As
long
as I log onto a secure network with a username and password, the email is
sent.

However, I recently moved to wi fi and when I log onto a public network ie
no username and password, I cannot send the email. I am able to retrieve
the
mail. Outlook spits out an error along the lines of an error with the
server.

What do I do.

Thanks

Kenny
