Turn on moderation and disable the + usage then. HKCU\Software\Microsoft\Office\[14.0][12.0]\Outlook\Options\Mail\DisableDLExpansion=1
Or change the DL's to dynamic...I THINK dynamics cannot be expanded. Test that idea. Nothing is going to be perfect, they can still grab from the GAL.....then you put limits on numbers of recipients....then they send multiple messages or forward all the addresses to their gmail account....non-ending battle. So be sure to clarify to the powers that be is all you can do is make it harder on the disgruntled person.

We're trying to find a solution for future disgruntled employees. A situation hasn't happened yet, but upper management wants us to take care of this on the technical side. The options below is all I have so far.

I can setup 'Message Delivery Restrictions' or 'Message Moderation', but that won't prevent the disgruntled employee from using the + in Outlook to expand the members of the distribution list. My other option is to hide the distribution list from the GAL to prevent the + from expanding the members, but that would inconvenience other users who need to send to the hidden distribution list if they don't already have it in their nickname cache. I'm out of ideas and would like to hear creative ideas from my fellow Exchange admins.
