Run the Inbox Repair Tool
What the Inbox Repair Tool DoesWhen you run the Inbox Repair Tool on a Personal Folders (.pst) file, it does the following:
Recovered Personal Folders FileAfter you run the Inbox Repair Tool, start Outlook by using the profile that contains the Personal Folders (.pst) file that you tried to repair. On the View menu, click Folder List to turn on the Folder List view. In your Folder List, you should see the following recovered folders:
These recovered folders are usually empty, because this is a rebuilt .pst file. You should also see a folder called "Lost And Found" (without quotation marks). This folder contains folders and items that the Inbox Repair Tool recovered. Items that are missing from the Lost and Found folder are beyond repair.

How to Recover Repaired ItemsYou should move as many of the items from the Lost And Found folder to a new Personal Folders (.pst) file in your profile. First, create a new Personal Folders (.pst) file entry in your profile and drag any recovered items from the Lost And Found folder to the appropriate location in your new Personal Folders (.pst) file.

How to Recover Items from the Backup Personal Folders (.pst) FileNOTE: If you cannot open your original Personal Folders (.pst) file before you run Inbox Repair Tool, it is possible that the following procedures may not work. If you are able to open the original Personal Folders (.pst) file, then it is possible that the following procedures may allow you to recover additional items from your damaged Personal Folders (.pst) file.
When you run Inbox Repair Tool, the option to create a backup of the original Personal Folders (.pst) file is selected. This option creates a file on your hard disk called <file name>.bak, and is a copy of the original <file name>.pst file with a different extension. The .bak file resides in the directory of your original Personal Folders (.pst) file.
You may be able to recover items from the .bak file that Inbox Repair Tool could not. Make a copy of the .bak file, giving the file a new name with a .pst extension, for example "Newname.pst" (without quotation marks).
Open Outlook using the profile that contains the your new Personal Folders (.pst) file from step 4 in the "Recovering Repaired Items" section of this article, and try to import the "Newname.pst" folder by using the Import And Export Wizard. To do this:
How to Recover a 2 GB Personal Folder (.pst)The upper limit of a Personal Folder (.pst) is two gigabytes. Often when a Personal Folder (.pst) approaches this limit, you may not be able to save or retrieve items. The same size limiitation applies to Offline Folders (.ost).
Microsoft has made a utility available that is designed to attempt to recover the stored items in the Personal Folder (.pst) by reducing its size below the critical limit. Use of this utility results in some data loss in order to recovery the maximum data.
