Public Folder Migrations and the Changing Cmdlets


To complete a public folder migration from Exchange 2013/2016 to Exchange Online you need to run

Set-OrganizationConfig -PublicFolderMailboxesLockedForNewConnections $true

But if you look at lots of the documentation that is out there with their tips and tricks etc. you will see that lots of them say:

Set-OrganizationConfig –PublicFoldersLockedForMigration $true

So very near – but its the wrong cmdlet now and it does nothing. It does not lock out the public folders and in the cloud all you get is:

PS C:\Users\BrianReid> Complete-MigrationBatch PublicFolderMigration
The public folders in the source environment are not ready for finalizing the migration. Make sure that public folder
access is locked on the source Exchange server, and there are no active public folder mailbox moves or public folder
moves in the source.
     + FullyQualifiedErrorId : [Server=VI1PR09MB2909,RequestId=ca0ffb4a-cc9f-4195-94fd-e3dd060587e6,TimeStamp=13/12/2018 18:03:00] [FailureCategory=Cmdlet-MigrationBatchCannotBeCompletedException] 2FB8651C,Microsoft.Exchange.Management.Migration.MigrationService.Batch.CompleteMigrationBatch
     + PSComputerName        : outlook.office365.com

And there is nothing useful on the web for this error, so I wrote this to help you get out of this hole!

Run the correct cmdlet and migrations will start!

    What about when I ran the
    Set-OrganizationConfig -PublicFolderMailboxesLockedForNewConnections $true

    and I stil get the error about folders not being locked after 36 hours. I tried restarting information store / dismounting& mounting database again, restart the Exchange server, but nothing.

      I would open a support case then. It would appear that the sync of the latest state of the folders is not being replicated to the tenant, or the tenant is looking at a different public folder infrastructure.

    Mine ended up being a mailbox move request that had not be removed.
    Get-MoveRequest
    Get-MoveRequest |Remove-MoveRequest
