Outlook share same manager

I know that I've seen somewhere in Outlook that I've been able to view a list of other people that share the same manager as a given person. It's useful for locating a peer of someone who's on vacation, etc.

I'm not able to find it currently. I did a inteet search and both Bing and Google seemed to think I was asking how to share my calendar. Does anyone know how to do this?

Thanks,
