Outlook Web App didn't initialize. If the problem continues, please contact your helpdesk. Nullable object must have a value.
We had issues with a corrupt certificate. Had to uninstall OWA virtual directories and also from ADSI. I could not recreate the backend OWA from Command line so I did it manually in IIS. I also had to add OWA backend to ADSI so it might be missing some attributes, and not sure what they are.
Here is the issue I get now when logging into OWA on Exchange 2013
