Communication between Outlook and Exchange Server

[John]

Which tcp/udp-ports should initially be opened to let Outlook communicate
with Exchange Server 2003 when workstation with Outlook is coming from
another domain?

Thanks very much.

You actually need to define them as most of the conversation is handled over
dynamic ports.
