Then being new to this, my question would be, how do I leave a copy
on the server? I assumed if Netscape is not open (so does not
download messages until I open it) that the messages should go to
Outlook.

That's a fairly safe assumption.

And that would not answer the question as to why some go
through and some don't, would it?

You could enable Outlook's diagnostic logging and see enactly what the
client and server tell each other about the number of messages awaiting
download. http://support.microsoft.com/kb/300479/en-us
