Sending' reported error (0x8004210B)

[mko57]

I am unable to send messages from Outlook 2003. This just began one week
ago.
I do have multiple email address in Outlook 2003 and only one account will
send. The other three will stay in my outbox forever.
Error Message:

If you have an antivirus scanner configured to scan incoming mail, uninstall
that AV program and reinstall it without the mail scanning feature. See if
that makes a difference.
