We are running Exchange 2007 plus each client uses Outlook 2010. Now one of the users has created a Contacts list under the Public folder and this is visible across the company. All the users have the correct permission we think as everyone can add, edit and delete contacts without a problem. The problem that we have that is that when we go to one of our DL's and want to add a new member the new contact is not showing up nor is it showing up when you create a new mail and look in the address book. It is however showing up if you just do a search for it in the Public Folder Contacts from any of the company computers.
