I have recently performed a migration of a SBS 2003 server to SBS 2011 server which mostly went as planned. The public folder did not end up working quite right and now I am faced with a variety of small issues related to the shared calendar, plus I have remnants of the old 2003 server still showing up, but that machine is now long gone. I would like to configure the system to forget the old server (replication) and fine tune the public folder to be accessible and allow edits from Outlook 2010 and OWA. I am not using any older clients, but do have clients connecting with IOS and Android. The shared calendar is currently only accessible from Outlook when locally logged into the domain (or via remote access to a locally logged in PC) and even then, I get complaints from users who can't make changes to items they created in the calendar. Where do I begin?
