Hello, I have a problem accomplisching the following: I want 2 groups of users separate from each other. One group cannot see the other users in there global adresslist. So I did the following: I created a new storagegroup, named "x". I created a new mailboxstore I created a new public store and new public folder tree. I created a new mailboxstore and a new public folders store. I created a new adresslist I created a new offline adress list I created a new global adress list and linked al these adress lists to each other in the properties. But now when I lookup the properties of the new mailboxstore I see that the default public folder is still linked to the original already existing public folder. When I try to change this I get to see a list of public folders but it only shows the first public folder store.. And when I test it with a new created user in the new mailbox store I stell get to see the users of the other storagegroup in the adresslist. Does anyone know what step I missed? Thanks in advance, Mark.
