I have configured my notebook (Windows XP Home SP2) and Outlook 2003 to
communicate with our Exchange 2003 Server via RPC over HTTP. It works fine if
i connect the notebook to our LAN or dial in directly via RAS. If i use
another internet provider i get no connection.

Any ideas ?

When you are connected to the LAN or RAS, start Outlook with the /rpcdiag
command line switch and verify that you are connecting via RPC/HTTPS. If
you get a TCPIP connection, then you can start with the basic checks (e.g.
Open Internet Explorer and type: https://fqdn.of.server/rpc. Do you get a
security alert dialog about the certificate? If yes, Outlook will never
connect until this problem is rectified.)
