Dear All, I am still new to Exchange server, so Please can any one help me to understand that ? I have one thing which makes confuse, please some one try to correct me. What do you mean by Virtual server? And what do you mean by POP3 virtual server? For Example, if I have here in Saudi Arabia My Exchange server and it has the following Real IP ( 192.168.1.185 ) and its online by ISP through Fram Relay . And I have registered my new domain name under Network solution company with the following name ( MS400.com ) and it already registered , and they give me the following information :- Domain Name: MS400.com www.MS400.com Secure Server (SSL) Path: https://straw.site-secure.net/MS400/ Server Name: straw Web Directory Path: /www/MS400/ Current IP: 66.221.2.207 With the E-mail Solution . so I configured the outlook configuration to use the POP3 server which is my domain name . and I can send & Receive any E-mail with using Outlook Normal without my Exchange server at all . ( I mean connect online ). ======================================================================== ================================================== MY Question is Now if I want to configure my Exchange server which I have here in my office to be connected to My server which is located in USA and to download the E-mails only from My server in USA, when I configure THE Virtual server for My Exchange server , do you mean that , the virtual server for MY exchange server will be MY server in USA. I mean if its like I am telling My exchange server that , you have another virtual server located in USA with this IP 62.221.2.207 , Please go there and download all of the E-mails from there . and its POP3 virtual server . NOT SMTP virtual server . Is it Wright? Please littlie help regarding this . With my best wishes, Mohammed Tantawi IT Specialist
