To manage your public folders permissions, including the system folders if you still use them with Outlook 2003 clients, you no longer use PFDAVAdmin, but use ExFolders in replacement.
Some of the many new features that deserve to be underlined are :
- This can be run from an Exchange 2010 server only
- Can connect to Exchange 2010 or Exchange 2007 only, not Exchange 2003
- You can export properties of public folders and also export properties of all objects in a public folder
- Ability to connect to multiple mailbox stores at the same time to run bulk operations against multiple mailboxes across many databases at the same time
