Dear all I have installed the exchange massaging and collaboration on a member server on a domain. and every thing is ok. when I made a user name test and he is mail enabled. when I want to check the enternal email that is in his Mainbox at POP3 I receive at the client side when trying to access the POP3 Virtual mail Server that it needs the user name and password to enter the mail server (member server) and when I put the user name (test) and it's password it refuse. Can you tell me how can I authorize the test user to access the POP3 from a client using Microsoft Outlook. Best Regards
