Client Managed Distribution Groups

So previously, having a user manage the distribution group via Exchange 2007 and older, through Outlook was relatively easy. You just had to remember to tick the box in Active Directory, to allow them to modify the group.

Exchange 2010 and above has changed this "by design".

To resolve this, you need to download and run the Manage-GroupManagementRole.ps1 script, from TechNet.

Run the following from the Exchange Management Shell: Manage-GroupManagementRole.ps1 -creategroup -removegroup

This takes care of everything you need, and you can then use Exchange to control the groups that you wish users to be able to modify.
