I am working on a permissions issue. I gave a user O365 permissions of Groups Administrator, Exchange Recipient Administrator and User Administrator. I also gave them a role in Exchange Online that has the Distribution Groups role assigned to it. I want the user to be able to create and edit Distribution lists in Exchange Online. I have it were the user can build the Distro groups, however, they can't edit them. When they click to edit a group in the new Exchange Admin center and search for a user to add it returns no users found. However, if they use the classic Exchange Admin center they can edit the Distro groups successfully. I must be missing something here. What permission do I need to grant for the user to be able to edit the Distro group in the New Admin center?
