ID no: 00000000-0000-00000000, error code: -1056749164

When trying to export a mailbox using the Export-Mailbox powershell command I received the following error:

Export-Mailbox : Error was found for User Name ( because: Error occurred in the step: Moving mes
sages. Failed to copy messages to the destination mailbox store with error:
MAPI or an unspecified service provider.
ID no: 00000000-0000-00000000, error code: -1056749164

To resolve this issue you need to give the Administrator who is exporting the mail rights to the users mailbox.

Get-Mailbox "users mailbox" Add-MailboxPermission -User Administrator -AccessRights FullAccess


  1. Hi Clint... I've seen loads of ppl posting threads like this one on the net and the majority thinks that permission is the culprit. However, in my case I can successfully export mailboxes if i don't provide any switches like -senderskeywords in the commands. e.g. <> works just fine, but when adding -Senderskeywords (or any other switches) I see the error you encountered. Regards

  2. This was exactly the solution I have been looking for.. You have saved my day :-)

  3. I was exported many times and not changed configuration. My username was in Domain Admin and Exchange Admin group. One day I was received error with this error code number.
    In my case was corrected this:
    Get-Mailbox -Identity Name_my_mailbox | Add-MailboxPermission -User NameOfMyDomain\NameofMyUser -AccessRights FullAccess
    After this command I can again moved messages from mailbox. Thx.
