I'm trying to figure out how to customize the page that displays for a short time after your enter your credentials on the OWA (Exchange 2013) logon page and before your mailbox displays. I've made the logon page a different color the but this brief page still displays the default blue color.
The page displays "Outlook Web App" in the middle of the screen and has one of the loading circles displaying. It then says one of the following lines below the loading circle: Starting..., Still working on it..., Opening your mailbox... and Almost there...
Any ideas on how this page can be customized? I am not trying to change anything major. I just want to change the color.
