Can receive, but not send email.

EMails show as sent in the sent folder, but they are not being received by
anyone. Any guesses? I have checked smtp... I don't even get a test
message when sent.

When sending an e-mail, the item gets deposited into the Outbox folder. If
your sending mail server accepts your message that you send to it, Outlook
figures it got sent successfully and then moves that item from the Outbox
folder to the Sent Items folder (unless you configure sent items to get
stored elsewhere). Since you see the item got moved out of the Outbox
folder, Outlook got an +OK status back from the mail server. As far as
Outlook is concerned, it successfully sent your message. Your sending mail
server accepted it. That means you can't do anything about delivery of your
message because you are no longer in control of it.

As to WHO is the mail server might be in question. Normally when you send
e-mails, the account defined in Outlook has it connect to a mail server. If
you go back into that mail account in Outlook, is it still pointing at the
mail server you specified? If it got changed then you are sending your
e-mails somewhere elsewhere, like perhaps to a local proxy for your
anti-virus program. Some anti-virus programs will interrogate outbound
e-mails on-the-fly looking at the bytes in the traffic that passes through
their proxy. However, some actually pretend to be the mail server and
accept your e-mail there. If they find no problems with that message, they
then connect to the real mail server to upload your message to it. They do
that because they can then look at the complete e-mail content instead of a
few bytes at a time. But that also means when Outlook says that it
successfully delivered your e-mail that it wasn't to the real mail server
but instead to the anti-virus program's interrogator. You have to check the
logs for your anti-virus program to see that it had a successful mail
session with the real mail server. Your e-mail client sent your message to
another e-mail client (pretending to be the mail server) that then pretends
it is the e-mail client to send it to the actual mail server. As I recall,
McAfee operated like this.

You could disable the superfluous e-mail scanner in your anti-virus program
and retest. If that still fails, uninstall the AV program and do a custom
install where you DEselect its e-mail scanning function. Some AV program
will remain in the way even after you disable their e-mail scanner. Your
e-mail traffic still passes through their transparent proxy but simply
doesn't get interrogated, but if their proxy has a problem then your e-mail
traffic doesn't get through it. AVG is like that where you have to do an
uninstall an custom reinstall without their e-mail scanner to actually get
rid of it inserting itself in your e-mail traffic.
