I am trying to hide iCloud, Microsoft Exchange, Yahoo, Aol, and other account options within Internet Accounts. Does anyone have any idea how to hide them so users can't even attempt to login?
I don't know that it's possible to just hide or disable those options from within the Internet Accounts pref pane. Only way I know to stop it is to block access to Internet Accounts, which we do. Unfortunately not very many preference pane config profile options allow us to control things on such a granular level. Most times it's on or off in whole.
