Hi

When I send a mail in Outlook - to a valid email adress - I get the
following error from "Systemadministrator":

<recipients mail addres > den 19-06-2004 14:12

550 Error in User Lookup < recipents mail addres >

how do I fix this ?

OK - so either there's a problem with the recipient's email address or their
mail server, or there's a problem with your ISP's mail server (SMTP -
outgoing mail). Call your ISP or whomever manages your SMTP server and also
make sure you've configured it correctly in Outlook.
