Exchange distribution groups
We have lots of distribution groups, one for all students, all staff, each year group etc etc
Lately students have realised they can email these groups with stupid pictures so we need to lock it down a bit but it's proving more confusing than i first thought.
We need teachers to be able to email the All students group but disallow students from being able to email to any groups, but at the same time still be able to recieve from them.
I can see all the "accept messages from" settings, and that's fine as i want them to accept emails from everyone, but i need to be able to setup similar settings for outgoing emails, where do i do this? (please don't tell me on individual accounts or i'll cry)
Can anyone help me on this pretty please with a cherry on top? :)
