failure sending Internet email

I have one user in an office of 30 who cannot send Internet email using
Outlook (MS Office 2003 Pro). We use Verizon as or Internet email host and
have verified all the account and server settings in Outlook are correct. We
have verified that her Verizon mailbox is OK by using Verizon's webmail
interface to send without any problems. I have setup her account settings on
another PC using Outlook Express and successfully sent out Internet email
also. Verizon support suggested this could be due to a problem with where
Outlook stores the SMTP password for this email account. I have uninstalled
MS Office and reinstalled twice without any change in the problem. After the
second uninstal I manually deleted MS Office folders left behind by the
uninstall process before reinstalling.

Does anyone have a clue how to resolvel this problem short of a full system
reformat/restore?

Sorry, I forgot to give the specific error information.

When I click the "Test Settings" button in the Outlook account properties I
get:
"Send test e-mail message: Outlook could not logon to the outgoing mail
server (SMTP). The problem could be the server name, your server may require
authentication, or your server may not support SSL. Verify authentication and
SSL options under More Settings."

When I try to send an Internet email message, the "Outlook Send/Receive
Progress" window shows this error:
"Task ' - Receiving' reported error (0x800CCC0F): 'The
connection to the server was interrupted. If this problem continues, contact
your server administrator or Internet service provider (ISP).'"

This person has no problem receiving Internet email via Outlook, only
sending. The other 30 people in the office have no problems sending or
receiving Internet email.
