Exchange servers will not relay mail for you unless you successfully authenticate onto the server.

When you take the PC home you don't actually autheticate correctly onto that server / domain so it won't send for you.

What you need to do is:

In your E-mail Settings add "SMTP Server requires Authentication" depends on your version of office as to where that hides.

Log On Using should be set to your normal user name and password.

Provided the system isn't locked down more tightly that should work.

In Outlook Express, goto Tools, Accounts, Highlight your default account and click Properties, Server Tab,
near the bottom - check "My Server Requires Authentication".

That's it. This will allow you to send mail thru our server.
