CommVault 7 and Exchange 2007

I don't know how many of you out there use the commvault backup system however I know the process of getting it to grab Exchange 2007 mailboxes on Windows Server 2008 is quite the ordeal. However after much frustration I have a resolution and will document the steps.

1. Build Windows Server 2008
2. Install and configure Exchange 2007 mailbox role <-- important if you anticipate backing up Exchange data :)
3. Install and Patch the 64bit CommVault File System and Exchange database iData agents (the 64bit file system agent will be used to backup the file system)
4. Add the following Registry Hive: HKLM\SOFTWARE\Wow6432Node\GalaxyInstallerFlags
5. Add the following Registry keys underneath: DWORD bAllow32BitInstallOn64Bit = 1 DWORD bAllowMultiInstances = 1
6. Download and install the Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1
7. Disable UAC
8. Create a User account for the CommVault backup. The account must hold the following exchange roles: Exchange Org Admin, Exchange View Only Admin, Exchange Server Admin on the mailbox server.
9. Install 32bit CommVault mailbox, public folders (if using) and file system (required) iData Agents.
10. Make sure all iData agents are up to date.

That's it! 10 steps I know but when they aren't documented it's alot of guess work to go wrong.
