We are in the middle of a Exchange 2003 to 2010 migration. I have just been asked to find out what kind of access permissions have been granted by mailbox owners to other users. I have been using the tools available in Exchange 2010. I have also been using PFDavAdmin for Exchange 2003. But neither has been that grandular. I need to find out what permissions are on the subfolders under the inbox as well. Is there a tool out there can use to find the information I need?
