To use MS Outlook 2003 or Outlook Express with LimoWiz you will need an Internet provider that supports IMAP or POP3 support.  These two mail protocols are needed by Outlook. 

You need to find the incoming and outgoing mail settings from your ISP ( MSN, CompuServe, etc ).  
Visit your ISP website and they should provide you with a step by step instructions. We won't know these settings.
Test MS Outlook by sending email to yourself.

AOL users, please see Email with Microsoft Outlook or Outlook Express with AOL

If all OK, then you should be able to use LimoWiz to send email. Go to LimoWiz, Settings, and click the Fax/Email/Application tab. Select Email Program to Use and check all check boxes.

Now, you may send email from dispatch window and trip window. If email does is not sent, check Outlook Outbox folder. If messages are still there, it means Outlook is configured properly. If message are in the Sent Items folder, then the email message has been sent.
