Hi Jim! Hi Thomas! I can create two POP3 servers on Exchange 2003. But if they use the same IP address they cannot run together. If I click to start on secure POP3 virtual server I had the following warning message in EventView: Event-ID:1036 Type:Warning: Source:POP3Svc "An error occurred while starting the Microsoft Exchange POP3 Service: server instance number 2 failed to start with error 0x34." If I give different IP address for the second (secure) POP3 virtual server, then they can both start. Best Regards Mustafa
