I have a standard Server 2012 installed and installed Exchange 2013 onto it. On the RDP I can access OWA and it shows me the mailbox for the user currently logged in.
When I navigate my browser to my domain.fancy/owa from an external computer I just get a blank page in Chrome and Forbidden in IE.
If I try the ECP I get a server error. Does anybody know how to fix this problem?
Figured it out with various other post on the internet.
You have to disable SSL if you don't have HTTPS certificates. It tries to redirect the login to https://youserver.com and fails. That is why I got weird server errors, and forbidden.
Untick Require SSL on the Default Website and click Apply
It is best to get a SSL certificate if you running business or production.
I was able to resolve my IE issues logging into Exchange 2013 OWA by adding the domain to the trusted sites list in IE, however I have not had any success determining why I get a blank page after logging into Google Chrome. I do not have an issue with Mozilla firefox.
Just make to match the SSL Certificate in the Default Web site and in the "Exchange back end" site, this happens when you set a new certificate to services (IIS) but the change does not replicate into the "exchange back end" site so you have to do it manually.
Here's a Detailed "How To" in my blog: http://mcsemessaging.blogspot.mx/2014/12/blank-screen-after-login-via-owa-in.html
There is a log of documentation and causes for this issue.
One work around for me was to follow the advice in this redit post and this microsoft.com/forums
Set to disabled the following link.
chrome://flags/#disable-javascript-harmony-shipping
This works in google chrome
