Hi,

You can create an OWA custom theme to achieve your goal. These theme files are stored on the Client Access server in the installation directory in \Client Access\OWA\<version>\themes. Each theme is stored in a subdirectory of themes.

For more information, here is an article for your reference:

Hope this can be helpful to you.

Best regards,
