Public Folder permissions lost after Public Folder mailboxes are moved

In an Exchange 2013 organization running Exchange 2013 CU2 build 15.00.712.022 if you move a Public Folder (PF) mailbox the permissions structure on some PFs might be lost in the following situations:

If you move a secondary PF mailbox using New-MoveRequest, the permissions on any PF not stored in the secondary PF mailbox would be lost from the secondary PF mailbox and replaced by the default Access Control List (ACL). The original ACLs can be restored via a full synchronization event by running the following command:

Update-PublicFolderMailbox -InvokeSynchronizer <PF Mailbox> -FullSync

If you move the primary PF mailbox using New-MoveRequest, the permissions on any PF not stored in that PF mailbox are lost and replaced by the default ACL which gives Author permissions to Default authenticated users.

To work around this issue, install Exchange 2013 CU2 build 15.00.712.024 or later.
