Exchange 2007 and parental email addresses
We're moving towards using email as the predominant non-emergency/urgent method of contacting parents. We're collecting parental email addresses of the new intake and will apply this retroactively across the school as the contact information trudges in.
But I have a conundrum now. We'll have distribution lists for Year7Parents, Year8Parents etc and also the individual parents available as contacts in case a teacher needs to let a parent know about something.
So ideally, these contacts should be made available to teachers by some method, probably Exchange.
But we don't want the kids to be able to send random parents amusing emails.
But we do want little Joe Bloggs to be able to email Mrs Bloggs to ask if she can drop off his PE kit at lunchtime.
It's trivial to prevent the kids sending emails to a distribution list, but how do I prevent them sending emails to parents without hiding the contacts (approx 850 of them) from the GAL (and so making them unavailable individually to teachers).
Am I in ADModify / custom GAL territory?
Bonus question - how do I set permissions on who can see address lists other than the GAL? Say I create an address list called Y7Parents, based on Custom Attribute 1 (saying y7 parent, or whatever), can I restrict that list to just teaching staff?
