I was upgrading a Exchange 2003 to a Exchange 2007, but have some troubles move some accounts to my Exchange 2007 server, it fault whitch this error:
Summary: 1 item(s). 0 succeeded, 1 failed.

Error was found for XX because: Error occurred in the step: Preparing mailbox to be moved. Failed to copy basic mailbox information with error: The Microsoft Exchange Information Store service could not find the specified object., error code: -1056749241
Exchange Management Shell command attempted:

Some search on the internet and I found out that is using the address list to move a account. And that this users has been set to be hide from Exchange Address list, so removing this checkmark and now the user can be moved.
