I recently built out a new Exchange organization and encountered a problem I had never seen. I can't recall how many new orgs I've set up over the past two years, but this issue really stumped me. After prepping AD and installing the first Exchange 2010 server in this org I opened up the EMC to poke around and make sure everything was kosher before beginning service pack and roll-up installations. First thing I noticed was that only Organization was listed under Microsoft Exchange On-Premises, no server or recipient configuration. Next, upon expanding Organization only Hub Transport was listed. Finally, when highlighting Organization Configuration I was presented with the following in the middle pane:
You don't have sufficient permissions to view this data.
So after trying a few things (launching EMC from an admin shell, creating a new user account and adding to the organization management group, etc.) I realized that something had to have gone wrong during setup; permissions not being written correctly to AD or something. I decided to ask my mentor…google.
Among the first hits was a posting on the Microsoft Exchange Forum titled EMC Permissions Gone Part Deux which sounded darn close to what I had going on. After reading through the scary sounding disclaimer I decided to take the advice of the responder and check out the original post (EMC Permissions Gone) which had an exercise to confirm whether or not the permission issue was with RBAC or with the credential store within the local Windows installation. After following the procedure in that posting I confirmed that the problem was with the RBAC permissions written during setup and not in my credential store. I then followed (very closely) the process defined in part deux. After completing the re-writing of the RBAC role assignments I was able to launch the EMC and see what I was used to and launch get-excommand and have a full listing of EMS commands.
If you happen to run into something similar start with the instructions at EMC Permissions Gone first, and ONLY perform the procedure in EMC Permissions Gone Part Deux on a new installation of Exchange. If you are having a problem with an existing and populated installation of Exchange I would highly suggest you contact Microsoft Support for asstance.
