Outlook connects via HTTPS not TCP/IP when connected to LAN
Posted on 2007-08-06
On most of our laptops, I enable Outlook 2003 to be in cached mode, using the "Connect to my Exchange mailbox using HTTP" option. I always uncheck the "On fast networks..." and the "On slow networks..." using HTTP first options. I have found that on random occasions when setting up laptops this way, the laptops consitently connect via HTTP when on the Local Area Network (100MB speed). It's very annoying for the user, as it will ask them to log on each time they open Outlook. This is understandable when they are away from our office on a different network and want to connect, but why isn't the TCP/IP connection method not working when on the LAN? I am trying to give the user access to their exchange mailbox without using VPN when on the road, but I would like them to connect "normally" when in the office LAN, and logged into the domain. On occasion, I have found that if I disable the Exchange over the Internet option, then re-enable it, it start working properly. I do have a few computer working just fine, but there always seems to be a problem when we get new laptops in.
