Method 1: Inbox Repair Tool
A simple tool that has been around for a long time from Microsoft which basically tries to repair the header of the PST file and delete anything from the file it does not recognize or understand.
The tool is actually already installed on all Windows 2000 and XP computers in the following directory: (For Office 2007, it’s in C:\Program Files\Micrsoft Office\Office12\)
C:\Program Files\Common Files\System\Mapi\1033\NT
If it’s not in this directory for whatever reason, click on Start and perform a normal Windows search for the following executable, scanpst.exe. Now click Browse and choose the PST file that is corrupted. If you are not sure where your PST file is stored, it’s usually in this directory:
C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook
After selecting the file, go ahead and click on Start.
After it is completed, it will tell you the errors found in your PST file. Go ahead and click on Repair now to begin the repair of the file.
Now when you open Outlook, hopefully your Inbox will be back to normal and all of your email message will be there.
