I have exchange 2003 sp2 and I need some to type in the ports I need to have open for it.
I found an article from microsoft but really don't understand which ones I need open for my external firewall. So can someone please list the ports.
I am using pop3 connector, activesync(not sure if it is installed I need it though), smtp, outlook via the web.
this is for SBS windows and I am not sure if anyone knows what ports are needing for that too.
