I have a new installation of Exchange 2010 in place for an Exchange 2003 transition. This is our first attempt with SMBR and SME. Everything is working great until I try and connect to the target mailbox on a production 2010 Exchange server. The error says, "Unable to display the folder. You do not have access to view the contents of this folder". The user logged in has full access rights to the mailbox. Does anyone have any ideas why I can't connect to the live test mailbox?
