This short post summarizes a superb article on Exchange 2010 and single item recovery.
The bottom line of the article is that with Exchange 2010, you shouldn’t need to do single item recovery (also called granular recovery) from a secondary (or backup) medium. If I were an IT administrator, I know that I’d want to use the native Exchange functionality rather than go to a third-party for this.

Exchange 2010 Recovery Definitions
Store Soft Delete – this is when an item has been deleted from the Deleted Items folder and placed within dumpster.
Store Hard Delete – This is when an item has been marked for purging out of the store.
Hard Delete via Outlook (Shift-Delete) – This is when the end user performs a shift-delete on an item. This results in the item bypassing the deleted items folder and being directly placed in dumpster.
