Cannot move mailboxes: INSUFF_ACCESS_RIGHTS error
When moving mailboxes from Exchange 2003 to Exchange 2007 or Exchaneg 2010 either from Exchange Management Console or Powershell using the move-mailbox or new-moverequest cmdlets the move operation might fail with the following error.
Active Directory operation failed on server.domain.com. This error is not retriable. Additional information:
Insufficient access rights to perform the operation.
Active directory response: 00002098: SecErr: DSID-03150A45, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
+ CategoryInfo : NotSpecified: (0:Int32) [New-MoveRequest], ADOperationException
+ FullyQualifiedErrorId : 6C39B6E8,Microsoft.Exchange.Management.RecipientTasks.NewMoveRequest

At first sight it looks like the user initiating the move mailbox doesn't have enough rights to perform this operation, however that user can move other mailboxes just fine.
Here is how to solve the issue
Solved: Setup Exchange 2007 SP1 CCR passive node fails
When installing Exchange 2007 SP1 in Cluster Continuous Replication (CCR) configuration. The setup of the passive node fails with the following error:
"This is not a passive node. A clustered mailbox server represented by the cluster resource group [clustername] was found on this node."
I've found out that the reason for the problem is that upon finishing the Exchange Cluster installation on the active node the setup will ask you for a restart. Restarting the machine will cause the Windows cluster to failover to the passive node to be and thus causing the Exchange installation to fail on that node.
To solve this problem make sure to move back the cluster resources to the active node and re-run the Exchange 2007 SP1 installation on passive node.
This solution was tested on Microsoft Windows 2008 and Microsoft Exchange 2007 SP1
Give me 2 minutes and I'll save you hours of Exchange troubleshooting !
Disclaimer: Guys if you happen to be suffering from "Event ID: 494" syndrom on your Microsoft Exchange Server do not attempt anything before reading this article, I might save you a lot of time.
It is always frustrating to me to receive a calls from customers telling me that their exchange database is refusing to mount and that they have tried everything, even restored from their last backup but nothing seems to work! Oh if only they'd call earlier
Symptoms: Typically a storage group will fail to mount and an error will be logged in the Application Log with an event id of 494. The error is the following
