Exchange 2010 OWA does not work internally inside domain
Posted on 2014-04-21
Providing directions is appreciated....
Exchange 2010 OWA does not work inside the domain. Getting the generic page cannot display error in any browser. Even after clearing cache, history, etc. and flushdns. OWA works externally. Also, when I login with an account on one server, I get "A server configuration change is temporarily preventing access to your account. Please close all Web browser windows and try again in a few minutes. If the problem continues, contact your helpdesk."
We have 2 exchange 2010 servers [example... EX1 and EX2] in our environment and Godaddy SSL configured correctly. Both Exchange servers are with the same build version. All is working fine until recently. DNS is also hosted by Godaddy with [example... mail.domain.com] A host point to our exchange server.
In OWA settings, EX1 wih Internal URL EX1.domain.com/owa, EX1.domain.com/ecp, and External URL https://mail.domain.com/owa. EX2 also has Internal URL EX2.domain.com/owa, EX2.domain.com/ecp, and External URL https://mail.domain.com/owa. https://mail.domain.com/owa. Both server set to domain authentication (suspecting something here).
Within the domain, we used to be able to go to https://mail.domain.com/owa/ on any browser and login to owa. Same with our internal WiFi within the domain.
I may have missed some info but any assistant on pointing me in the right direction would be appreciated. TIA
