I have Exchange 2010, and I managed to mess up Outlook Web Access.
OWA and Outlook Anywhere were working fine with exception of Blackberry devices which were not able to authenticate using Blackberry Internet Service.
After troubleshooting this issue with Blackberry support tech they suggested that I should change Forms Based authentication as it is apparently not supported with Blackberry Internet Service.
I agreed to change that, and it did not fix the issue, and even after changing the setting back to original I have now more problems as no client can access the OWA.
When I try to access the OWA by going to:
I get initial screen where I can enter the user name and password, but afterwards I am presented with blank page instead of the contents of the mailbox, and the address bar displays: https://mail.domain.com/owa/auth.owa
It seems that my Outlook Anywhere is not affected as I am able to connect Outlook on my notebook through http proxy.
Any help with getting the OWA going again would be great.
