Can receive but not send e mail

[Oldschool]

Im using Outlook 2003. It was working fine for months. Out of the blue when
I send mail I get the following return message "Your message did not reach
some or all of the intended recipients". When I use test account settings in
Outlook everything tests ok & I get a return mail from Microsoft. Also, I can
send mail to myself & another user of the same ISP. My ISP asys everything is
fine with his e amil servers & the problem is with my PC. He's suggesting I
reformat!

I'd appreciate any help.

It sounds like authentication is required to send email outside of your
ISP's domain (and either this is a recent change and your ISP's tech support
is awful, or you accidentally turned the setting off).

In Outlook's menu, choose Tools - Email Account - View or Change - Next.
Select the account in question and click on Change. Next, click on More
Settings.

In the Internet E-mail Settings dialog, click on the Outgoing Server tab.
Click the checkbox that says "My outgoing server (SMTP) requires
authentication," and set the next option to "Use same settings as my
incoming mail server."

Does this fix it?

Herb, thank you!, thank you!, thank you! Problem solved. I'm going to send
this correspondence to my ISP. It's a small local guy providing wireless DSL
service. Thanks again.
