Exchange Public Folder Migration - Public folders not visible

Reading time <1 Minute

If the public folders in Outlook are not displayed immediately after a completed migration, it may be because synchronization is not yet complete.

With this command we start the synchronization manually:

Get-Mailbox -PublicFolder | Update-PublicFolderMailbox -InvokeSynchronizer

The result should be after a short time "true ” be:

IsHierarchyReady = true
IsHierarchySyncEnabled = true

Get-Mailbox -PublicFolder | FL name, * here *

Only when the result query is “true” on all mailboxes are all mailboxes synchronized. If Outlook were connected to the PFMailbox13, the public folders would not be displayed, but if Outlook were connected to the PFMailbox12, the public folders would also be displayed, because this is already synchronized.
