    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
      Get-MailboxExportRequest | Get-MailboxExportRequestStatistics
    4. Once export reaches to 100%, remove pst move request from the queue
      Get-MailboxExportRequest | Remove-MailboxExportRequest
