I have been trying to assign full access permissions to a mailbox based on a mail-enabled universal security group. I can add the group successfully either via the EMC or the shell. However, the users in that group never automatically see that mailbox in the left-pane of their Outlook. If I merely give a user permission to that mailbox it works like a charm.
My environment consists of Exchange 2010 SP3 with Outlook 2010 and 2013 clients.
Does anyone know an easy way to do this?
