I am not talking about the individual user themes they can pick for their mailbox but rather the overall theme for OWA pages like login or expiredpassword, etc.
So far I have found the directory where the default base theme is located:
..\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\owa\auth\15.0.712\themes
This has two directories "base" and "resources" which contain the images, css, etc.,
I can obviously go into that directory and swap out images / change css to customize it.
This method is described here:
Customize Outlook Web App
Here is a screenshot of the default theme owa login page (one of the pages I'd like to customize):
There just seems like there has got to be a better way to do this.
Does anyone know how to create a custom theme for OWA on Exchange Server 2013?
Also if it is possible, how to switch between themes?
Any help would be greatly appreciated.
