now it works for me too!
My solution for a dedicated Single MailBox Recovery server. (A Server without a Exchange installation)
1. Install SnapDrive (6.4.2) and check if you can manually connect a snapshot / LUN
2. Install Outlook
3. Install Exchange Management Tools
4. Install SME (6.0.4) and check if the windows service are running -> "SnapManager service"
5. DON'T install an SMSQL on this system!!! (It used the same service name as SME)
6. Install SMBR 6.0.3
7. Install/Update SMBR to 6.1
8. If you are use a secondary (SnapVaulted) Storage, check also the Switch Zoning!
