+ 0 Votes Outlook 2003 will not send e-mails. jlouis45 6 years ago I guess you need to check the connection settings for sending and receiving emails. Is your outlook setup through the network or is it a single user using internet dial up / Broadband connections. If you are using your network then click on the drop down arrow on your send/receive button on outlook and then click on dialup connection and then select Use LAN connection. Else select your dialup connection. Let me know the outcome if the problem is not fixed. Provide details of error messages if any.
