we recently installed an exchange server. Currently, our website is hosted by an external company, vendor. Since establishing our in house email system, i have an ongoing issue.
The issue is that I cannot access our website from within our network. I can access it from anywhere outside of our network but not from behind the router and server.
I know that there is some communication and pointing-referring from the web host and our mail server and i am wondering what could have caused this. My webhosts claims no responsibility in this and can provide no answers.
(i am not an it guru so please be gentle.)
