The MailboxExportRequest cmdlet is available to run in the on-premises Exchange Server only. It can export the content from primary mailbox and archive mailbox to a PST file. But, this cmdlet is active in Mailbox Import Export Role only. This role is not a member of any role group by default. If you are an Administrator, then you need to add the Mailbox Import Export Role in the Role Group.

  • In the Exchange Admin Center, go to Permissions, then choose Admin Roles.
  • Select the Role Group where you want to add the role and click Edit.
  • In the Role section, choose Mailbox Import Export Role and save the changes.
  • Save the Changes in the Admin Roles and come out of the wizard.

If the cmdlet is stuck in the process due to problems in the source mailbox, then there are several parameters that can solve them. Some of the important parameters are-

  • -AcceptLargeDataLoss: The parameter will allow the cmdlet to run even if a large number of items in the source mailbox can’t be copied. You do not need to input a number of items in the switch.
  • -BadItemLimit: Bad Items Limit shows the corrupt items in the source mailbox that can’t be copied in the PST file. The parameter will set a number of bad items that are allowed before the request will fail. You can set the bad item limit and manage the faulty items in mailbox.
3rd Method
  1. One solution that you can try is choosing the ‘Run as Administrator’ by right clicking on EMS icon rather than using a shortcut for it. After that ensure that login credentials are also accurately written. EMS runs only with administrator rights with correct login credentials.
  2. Install SP1 and update Exchange if not done earlier as this is required to run the mailbox request command. Once updated, restart the EMS to see any difference.
  3. While writing the commands, check the credentials are accurate without any error in spellings. Domain Name has to be specified correctly within the command.
  4. The account should be given the ‘Import Export Mailbox’ role for the export request.
    1. Assign the permission with this command
      New-ManagementRoleAssignment –Role “Mailbox Import Export” –User <domain >\ <username >
    2. Now run the export cmdlet, save to local path in this cmdlet
      New-MailboxExportRequest <username> -Filepath \\<server>\location\<filename>.pst
    3. Look at the .pst export progress executing the following command
      Get-MailboxExportRequest | Get-MailboxExportRequestStatistics
    4. Once export reaches to 100%, remove pst move request from the queue using this command
      Get-MailboxExportRequest | Remove-MailboxExportRequest

Here provide the respective details like – domain, username, server, location, filename, etc. as per assigned to the account in the Exchange Server for all of the above commands.
