Exchange Mailbox Moves: ‘FailedOther’ Stops at 95%

KB ID 0001376


If you don’t see this happen at least once in a migration I would be surprised!


  • StatusDetail: FailedOther
  • PercentComplete: 95%



 You can remove the move request and start it again, with both a BadItemLimit and AcceptLargeDataLoss flag, (these might seem scary, but I’ve migrated many thousands of mailboxes, and never seen a problem.)

But the mailbox is massive and it had been moving for hours! OK, we can change the parameters, and resume the move as well!

Option 1 (Remove and Restart the Move)

Remove-MoveRequest -Identity user-name

New-MoveRequest -Identity “user-name” -TargetDatabase “target-mailbox-database” -BatchName “user-name” -BadItemLimit “200” -AcceptLargeDataLoss

Option 2 (Resume Existing Mailbox Move)

Get-MoveRequest | ?{$_.DisplayName -eq “user-name“} | Set-MoveRequest -BadItemLimit 200 -AcceptLargeDataLoss

Get-MoveRequest | ?{$_.DisplayName -eq “user-name“} | Resume-MoveRequest

PowerShell - Resume Move Request

The move should now restart/resume.
