Monitor Move Requests

To monitor move requests, run this command…

 Get-MigrationUser | Get-MigrationUserStatistics
Get-MoveRequest | Get-MoveRequestStatistics
PS Di spl ayName Hyb User I PS Get-MoveRequest I Status Detai - AutoSuspended Get -MoveRequ est St ati sti cs TotalMai boxSi ze 2.479 MB by... Total Ar chi vesi ze 0 8 (O bytes) Per centCompI ete
  • Once the status turned to AutoSuspended and if your user has new emails coming you may run the Resume-MoveRequest

for the user or if you want to stop the move request you can user the Suspend-MoveRequest cmdlets

Suspend-MoveRequest -Identity “EMAIL_ADDRESS“
Resume-MoveRequest -Identity “EMAIL_ADDRESS“

*using Resume-MoveRequest, the batch will be autocompleted hence the user will now be an O365 mailbox

Resume-MoveRequest -Identity “EMAIL_ADDRESS” -SuspendWhenReadyToComplete
