Exchange 2007 - Block mail by group

[mitchell1981]

We have recently upgraded from Exchange 2003 to 2007.

 

We have distribution lists (security groups) set up for each year group in the school. We allow staff to send mail to year groups, but we don't allow students to send mail to the whole year group for obvious reasons.

 

This worked fine in Exchange 2003, and the mailboxes have moved over with the correct settings as shown in this screen shot of the 'Mail Delivery Restrictions' box.

However, I've tried to do the same with the newly created year 7 group, and the dialogue box will not let me add in the staff group (or any group) as an allowed group. All I see is a list of individual users.

Anyone know what's going on?

 

Thanks.

No one got any ideas?

 

If this is not possible with 2007, how do other schools stop students sending messages to all staff, all students etc..

 

Do you restrict using the maximum recipients options?

I;ve got this set up on mine with Exchange 2007 - the groups are distribustion groups in ad with a Universal Scope.

 

I can still do all the security stuff as well.

I've had a good look and mine are looking alright too. My Exchange has been a little sluggish in displaying new accounts to mail-enable though, accounts I created Wednesday morning are still slowly popping up as available..

I am limiting max number of recipients just for students..

Get-Mailbox -OrganizationalUnit "Students" -ResultSize Unlimited | Set-Mailbox -RecipientLimits 3

You can't just pick an AD group, it has to be a distribution list as the source for blocked users.

Thanks for suggestions.

 

Turns out that the problem was that the groups were global groups, but needed to be universal groups. Not quite sure what difference that makes, but it fixed it anyway. They now all appear in exchange.
