Cant send mail. Tried everything I'm lost here

[DoDaMan]

I have everything set up like Verizon tells me to. I can receive emails but
not send. I use outlook and Vista 64

Heres the message.

What AV software are you using? Disable any real time mail checking
features. If it's Norton or McAfee, they are notorious for causing mail
issues.

I have no AV on this comp. Could it be windows defender? If so, what settings
need to be changed?

You use "outlook"? I'm assuming you mean Windows Mail.
Go to Tools, Accounts, select that mail account, Properties, Servers.
Put a check in the box for "My server requires authentication".
