We're finishing up a dual-sing migration from Exchange 2003-2010-2013, and I just finished moving the last of the mailboxes from the Exchange 2010 server to the 2013 server. For some reason, even though we don't have any Outlook 2003 clients, it created the public folder database when I did the Exchange 2010 install. We don't use or need them a all, as ALL of our email clients are at least Outlook 2010 SP2. The only "public folders" there are, on the 2010 server are the system ones that are created during the installation: the 1"Default Public Folders" one: Internet Newsgroups, and the 5 "System Public Folders" ones: EFORMS REGISTRY, Events Root, OFFLINE ADDRESS BOOK, SCHEDULE+ FREE BUSY, and schema root. Can I just delete the database from the 2010 server and not worry about moving anything to the 2013 server? Everything I've read leads me to believe I can just delete everything, and not worry about them... Thanks for any input.
