Get-mailboxrestorerequest

Thegood news is that the new scheme works for both on-premises and cloud deployments. As usual, migration is a bit of a pain, but once you have moved the older public folders across to mailboxes, everything works quite nicely as long as you have clients that understand how to access the new content. For now that means Outlook 2013 or Outlook Web App.

The first public folder mailbox created in an organization holds the primary or writeable copy of the folder hierarchy. All other public folder mailboxes contain a not-writeable or secondary copy of the hierarchy that are updated by an Exchange mailbox assistant every 24 hours at a minimum, or every 15 minutes if clients are connected to a public folder mailbox that contains a secondary copy of the hierarchy.

Synchronization ensures that all of the public folder mailboxes present the same hierarchy to clients. By reference to the writeable copy, public folder mailboxes that hold secondary copies learn about additions and removals of public folders and the mailboxes that hold public folder content. The older form of public folders also synchronize information between databases but use replication messages for this purpose. By contrast, Exchange 2013 synchronizes public folder mailboxes by connecting to the mailbox that contains the primary hierarchy and adjusting a secondary copy based on the primary.

get-mailboxrestorerequest shows that it completed. However, I have no subfolders and there were a lot. There were no emails originally in the root folder so the only thing that I can see that was restored are the permissions that were set on this folder from the backup.
