I am installing Exchange 2007 mailbox server on CCS running on windows 2008.In mysite I have Exchange 2003 running and Exchange 2008 transport/CAS hasup and running. I follow this link (http://technet.microsoft.com/en-us/library/bb676458(EXCHG.80).aspx)toconfigure cluster and install first active mailbox on CCS. Installation runs pretty smooth without error. At end of first active mailbox install, I run Stop-ClusteredMailboxServer command to make mailbox server offline then reboot machine. After server reboots, WhenI run Start-ClusteredMailboxServer to start mailbox server, I got following error: WARNING: An unexpected error has occurred and debug information is beinggenerated: Object reference not set to an instance of an object.Start-ClusteredMailboxServer : Object reference not set to an instance of an object.At line:1 char:29+ start-clusteredmailboxServer <<<< EXCH7 Anyone have this same problem? Thanks

By "ccs" may I assume you mean Continuous Cluster Replication (CCR)? Of course by Exchange 2008 you mean 2007. I think it might be a powershell issue. You could try running it from another machine that has the management tools installed. You can also read here asI think this is the same issue: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=2374058&SiteID=17

You are right it is CCR and Exchange 2007. Sorry, too many typo. I run Start-ClusteredMailboxServer command on both Exchange management console and Shell. They both got "Object reference not set to an instance of an object" error. When I run it on shell with -verbose switch, I got following results: [PS] C:\Windows\System32>start-clusteredmailboxServer -Identity:exch7 -verboseVERBOSE: Start-ClusteredMailboxServer : Beginning processing.VERBOSE: Start-ClusteredMailboxServer : Administrator Active Directory sessionsettings are: View Entire Forest: 'False', Default Scope: 'aegislimited.com',Configuration Domain Controller: 'dc4.aegislimited.com',VERBOSE: Start-ClusteredMailboxServer : Searching objects "exch7" of type"Server" under the root "$null".VERBOSE: Start-ClusteredMailboxServer : Previous operation run on domaincontroller 'dc4.aegislimited.com'.WARNING: An unexpected error has occurred and debug information is beinggenerated: Object reference not set to an instance of an object.Start-ClusteredMailboxServer : Object reference not set to an instance of an object.At line:1 char:29+ start-clusteredmailboxServer <<<< -Identity:exch7 -verbose Error happened At line:1 char:29. What this mean? Where can I find this line1: char:29?

Thanks for reply. In my case, I just installed exchange 2007 on first node. After reboot I failed to make mailbox server online because of this error. Exchange 2007 have not been installed to second CCR node yet. And I never run Enable-ContinuousReplicationHostName on both cluster node yet.

Dear customer: Based on my knowledge, the complete command of Start-ClusteredMailboxServer is like the following, make sure you assign Identity parameter to it.

EXBPA log shows EXCH7 cannot be contacted because EXCH7 is offline(I cannot make it online.) Good news is I can make it online now after I run Cluster Group move command. Thank you very much.

Dear customer: I am so glad to know the issue has been solved. It's been a pleasant experience working with you. Thanks again and have a great day! Rock Wang - MSFT
