Exchange 2013 CU2 Issue – Public Folder Permissions Loss After PF Mailbox Move

Exchange Team Blog inform about some issue when you install CU2 for Exchange 2013 and you use Modern Public Folders.

This issue can occur when you move public folder mailboxes.

When you move public folder mailbox it’s possible that you will lost permission structure on some public folders, specially:

  1. If you move (via New-MoveRequest) a secondary public folder (PF) mailbox, the permissions on any public folder (including well known folders) not stored in the secondary PF mailbox would be lost from the secondary PF mailbox and replaced by the default ACL. The original ACLs can be restored via a full synchronization event by executing Update-PublicFolderMailbox -InvokeSynchronizer <Public Folder Mailbox> -FullSync.
  2. If you move (via New-MoveRequest) the primary PF mailbox, the permissions on any public folder (including well known folders) not stored in that public folder mailbox are lost and replaced by the default ACL.

Exchange 2013 CU2 – mailbox databases limit changes

Administrators of Exchange 2010 who have more than 50 databases can now be happy.

Exchange 2013 enterprise has limit of 50 databases per server, but not with CU2 !!!!

Exchange Team has released that many of us have Exchange 2010 environments with more than 50 databases. And during migration to Exchange 2013 enterprise it could be a problem to decrease number of mailbox databases to 50 per server.

So when you install CU2 for Microsoft Exchange 2013, mailbox databases limit for enterprise version will be increased to 100.

CU2 is expected later this summer.

CU2 won’t change number of databases pers server for standard edition, and it will be 5 per server.
