Announcing Public Folder Migration Scripts with Modern Authentication Support
Hello Exchange Public Folder Team,
We are currently trying to use 'Sync-ModernMailPublicFolders.ps1' for the first time since the old script, 'Sync-MailPublicFolders.ps1', isn't working anymore since basic auth is deprecated. When running 'Sync-ModernMailPublicFolders.ps1' with the -WhatIf switch, we're seeing the following output:
"The following local mail public folder changes were detected and will be applied to Exchange Online: 390 object(s)
created, 0 updated and 390 deleted. Do you really want to proceed?"
The result from this script is quite different from when we ran the original 'Sync-MailPublicFolders.ps1' script. The main concern is that the modern script is saying it's creating 390 objects, but then deleting 390? Is this normal? If this is normal, are we going to lose any permissions that were created in Exchange Online for these on-premise mail enabled public folders, such as SendAs rights, during the deletion and creation when running this script?
