Your post is devoid of details that could reveal where you have an issue. I can't know what your EMAIL and ISP's requirements are for such settings and nothing was written about your LAN, where the EMAIL SERVER is and how traffic gets from here to there.
Maybe a call to your ISP is needed.

I am trying to set up Outlook to work with a LAN connection. I set the account to connect via the LAN but it still gets disconnected.
Any help will be appreciated.
