If it's an Exchange server, you'll need to set up Outlook to connect correctly and it should automatically view the messages when opening Outlook.
If you're using a standard POP3 mail server, then you may need to change some settings to let it automatically attempt a "Send/Receive" every few minutes. Unfortunately, you didn't tell us which version of Outlook you're using but on this Outlook 2003 machine, open Outlook, then click on "Tools" in the upper left, choose "Options", then click on the "Mail Setup" tab. In the "Send/Receive" section, be sure place a CHECK mark in the box next to "Send immediately when connected". Next, click on the "Send/Receive" button in that section and make sure there is a CHECK mark next to the box which says: "Schedule and automatic send/receive every X minutes". You may also need to CHECK the box which "Sends/Receives" while offline.
Hope this helps.
I have a DELL GX270 using Microsoft XP, and I had a problem with my computer yesterday where I had to remove Microsoft Office and then reinstall it. Everything is OK, except for Microsoft Outlook. My new emails do not show up when I turn on "Outlook" unless I hit the ?send/receive? tab. They previously use to display automatically when I started up Outlook. In addition, I am not notified when I get a new incoming email. I have the tab checked in the advanced settings where it says to show notice for incoming mail, but it is not doing it. Could you suggest something?
