I am in the middle of exchange migration, current setup allows for both servers 2003 and 2010 in the same organization.
I have had no problems migrating all but on mailbox so far. When I attempt to migrate this mailbox an error message displays:
Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:01
Active Directory operation failed on DC4.EXAMPLE.COM. This error is not retriable. Additional information: Insufficient access rights to perform the operation.
Active directory response: 00002098: SecErr: DSID-03150BB9, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
The user has insufficient access rights.

When an item can't be read from the source database or it can't be written to the destination database, it will be considered corrupted. By specifying a non-zero BadItemLimit, you are requesting Exchange not copy such items to the destination mailbox. At move completion, these corrupted items will not be available at the destination mailbox.
Exchange Management Shell command attempted:
'EXAMPLE.COM/Employees/EXAMPLE/User One' | New-MoveRequest -TargetDatabase 'database2' -BadItemLimit '50'

domain admin and $exchange2010 server have full access to the datastore this mailbox is located in. All other mailboxes from this data store were migrated without a problem.
Appreciate any help.
