Question : Exchange 2010 ports - What firewall ports need to be open
Hello Experts,
Trying to get some questions knocked out for my Exchange installation. I have been getting some excellent help and I'll hopefully be closing many questions shortly.
Question: What outside internet ports need to be opened for Exchange 2010 to work behind a firewall? I have port tcp 110, 25, 993,995, 563,80,443, 465
I'm reading this article

I don't have an Edge Transport Server so i would just be the Hub Transport server role connected directly to the internet behind a firewall.
I also need to connect with OWA
Answer : Exchange 2010 ports - What firewall ports need to be open
For OWA/ActiveStn you would be using port 443
you need port 25 for your SMTP
you shouldnt need POP3 or IMAP but if you do then:
POP3 110
SSL-POP3 995
IMAP 143
IMAPS 993
SMTPS 465
but there should be no need for these
