I have an Exchange server at school. There is a global limit on the number of recipients for e-mails set to 500. This enables members of the staff to send messages to all pupils. I need to set the limit for pupils to a much lower level than 500 to prevent them spamming hundreds of fellow pupils (yes - I've had complaints from those on the recueiving end!). Is there a way to set the limit without having to go through every one of them individually? Thanks for any help.
