Exchange 2007, the GAL and students

[Divaldo]

We are running Exchange 2007 with Outlook 2007 and OWA for all users (staff and students).

Recently our lovely students have realised that they can see all the staff DLs on the global address list and email whatever they like to all our staff. I was wondering if anyone knew a way of either stopping them seeing the GAL completely, or creating a rule to stop them sending to more than 3 people at once.

The staff are all in one OU, the students are all in another. The students are all in a security group named 'students' if that helps.

Many thanks.

Yes you can do the "restrict number of people" sent to at once...

Excellent, thank you. Will this work with security groups? Or do i need to put my students in a DL or mail enable the current group?

You can also define permissions on lists, so only staff can email staff groups for example.
