If you are able to open the original .pst file, you may be able to recover additional items from your damaged .pst file. By default, the Inbox Repair tool creates a file called file name .bak, which is a copy of the original .pst file with a different extension. The .bak file is located in the same folder as your original .pst file. You may be able to recover items from the .bak file that the Inbox Repair tool could not recover. Make a copy of the .bak file, giving the file a new name with a .pst extension. Import the "bak.pst" file, and then move any additional recovered items to the new .pst file that you created.
