Hello, I read that from this tool one can export item/folder properties and import back, but why should I need to do so ? can someone tell me of a situation where I might need this tool ? Thanks

Here are some good articles about ExFolder, they all have similar information. To answer your question about when one may need to import export folder properties - is when you are troubleshooting any issue with a mailbox or folder and you don't want to restore items but you are only interested in settings of a folder. http://blogs.msdn.com/b/brijs/archive/2010/05/12/where-is-pfdavadmin-for-the-exchange-server-2010-exfolders-is-here-now.aspx http://thoughtsofanidlemind.wordpress.com/2010/09/27/the-very-useful-exfolders-utility/ a situation where you might need it. http://blog.ronnypot.nl/?p=169 also granting permissions, adding replicas (EMS can be used for most of these tasks but exfolder gives you familier GUI interface.)

Sometimes ExFolders ( and pfdavadmin depending on Exchange version) are the only ways to restore a deleted public folder.
