exchange 2010 - maximum recipients
After about a year of having exchange 2010 in place we've only just noticed that we haven't changed the settings for students maximum recipients....bit of an issue when one rogue student deciding to send naughty images to all the other students in the school >_<)
Now on exchange 2003 back in the day, i remember a way of freely stopping students being able to send to both groups and to more than 2-3 other people. I can find the "maximum recipients" setting on exchange 2010 but that's per mailbox, is there a universal method for applying this to all users of a particular security group or applying it to all mailboxes within a mailstore (students and staff are in seperate stores)?
EDIT: oh and a method for stopping students from being able to send to particular groups too.
