Hi! I have problem with multiple POP3/IMAP4 virtual servers on Exchange 2003. I have Default Virtual Server POP3/IMAP4 and wanted to create the second secure server with the same IP address. The created second virtual server (POP3 or IMAP4) cannot be startet. There is an eventview warning: Event ID: 1036 Source: POP3Svc Category: General Error-Massage: ?An error occurred while starting the Microsoft Exchange POP3 Service: server instance number 2 failed to start with error 0x800cc801.? All my port and IP configurations for virtual servers are correct. I have the following configurations for POP3 virtual servers: Default Virtual Server: IP: 10.10.4.1 Port: 110 Second Virtual Server: IP: 10.10.4.1 Port: 995 Certificate: yes There is also NO virus scanner which can have negative influence on virtual server. There is also NO certificate problem!!! I tried to create the additional virtual servers on three different Exchange 2003 servers. No chance! On each server I have the same problem!!! How can I solve this problem? Is that perhaps a bug in Exchange 2003? Best Regards Mustafa
