Hi All,

I have set up an additional Exchange 2007 server onto my Domain and need to migrate all of the existing users around 15 over to the new Exchange database. I have used the 'move' option within the mailbox settings but am getting an error as follows:

Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:46:54


Error was found for <mailbox> ( because: Error occurred in the step: Moving messages. Unable to unlock mailbox with error:
MAPI or an unspecified service provider.
ID no: 00000000-0000-00000000, error code: -1056749254

Exchange Management Shell command attempted:
'<Domain>/<Container>/<Mailbox' | move-mailbox -BadItemLimit '100' -TargetDatabase '<ServerName>\First Storage Group\Mailbox Database' -GlobalCatalog '<ServerName>' -DomainController '<ServerName>'

I am logged on as a Domain Admin, the Domain admin has full access rights, the user I am trying to move has 'allow inherit...' set in security, I have the old Exchange box sat next to the New Exchange Box on the same switch. I have ensure that there are NO limits on the target mailbox store. I have been able to move some users but when I try to move others I get this error. Also I had this error on one user then tried it again and it worked so this looks to be a networking issue to me. I have also tried moving two seperate users with two seperate move wizards running and they both fail at exactly the same time which is why I am guessing it is a network issue.

I have read through various blogs and one in particular suggested to 'dump' as the transfer takes place but no description on how to do this let alone what it actually means.

I have been working on this now for 3 days solid and really need to get a solution.  The worst case scenarion is that I export the users PSTs then move the mailbox configuration settings only to the new server. The problem with this is that I am paranoid about losing emails for my customer. If I go down this route and no-one can help with the original problem can someone give me some guidance on best practice on doing this.

Sorry it is so long a question but I needed to get all the details in...

Thanks in advance
