Outlook 2000

When I type a new email and click send it goes to the outbox and stays there until I click send/receive. Someone told me to fix that by going to TOOLS, OPTIONS,MAIL SERVICES and there to set the sent immediately or how often to check messages. However, when I follow that procedure I do not get those options on that window. If I follow TOOLS, OPTIONS,MAIL SERVICES I get the following options:
Startup Settings
Mail Options: Check for new mail on Internet E-mail - My Server is named.

Thanks for any advise you can give.
