Ive recently installed exchange 2010 in an old 2003 organisation, Ive migrated all the mailboxes and replicated all the PF's. All is working well as it is but I want to uninstall the old 2003 box. The only problem I have is if I shut it down then the clients are still looking for the 2003 box for thier public folders even though I have replicated them and they are on the 2010 box? Would this sort its self out if I uninstalled the 2003 box??
