I am having a weird issue: I have a site with a DC/Exchange (server 2003) and Terminal Server 2008.
DC/Exchange is running Windows Firewall.
I opened all known and recommended ports to allow Exchange, I added Microsoft Outlook to the list of allowed programs, yet, users who connect to Terminal Server are NOT able to open Outlook, or if they open it, e-mails get stuck in the Outbox.
As soon as I disable the Firewall on the DC/Exchange, everybody can access Outlook and e-mails flow...
What port/application am I missing to open in Windows Firewall?
