PS C:\> Get-MoveRequest -BatchName "MigrationService:MigrationBatch01" -ResultSize Unlimited | Get-MoveRequestStatistics

DisplayName    StatusDetail TotalMailboxSize               TotalArchiveSize PercentComplete
-----------    ------------ ----------------               ---------------- ---------------
