Someone needs to take a look at settings, and from an accessibility standpoint. What you describe is nothing like what the defaults typically are with any version of Office I've worked with. I suspect that someone has decided to "get creative" with how they're setting things up in the organization without every having thought about accessibility at all.

It is the function of creative men to perceive the relations between thoughts, or things, or forms of expression that may seem utterly different, and to be able to combine them into some new forms--the power to connect the seemingly unconnected.
