Start Outlook using the profile that contains the .pst file that you tried to repair.
On the Go menu, click Folder List.
In the Folder List, you may see a Recovered Personal Folders folder containing default Outlook folders or a Lost and Found folder. The recovered folders are usually empty, because this is a rebuilt .pst file. The Lost and Found folder contains folders and items that the Inbox Repair tool recovered. Items that are missing from the Lost and Found folder cannot be repaired.
If you see a Recovered Personal Folders folder, you can create a new .pst file, and then drag the items in the Lost and Found folder into the new .pst file. When you have finished moving all items, you can remove the Recovered Personal Folders (.pst) file, including the Lost and Found folder, from your profile."
