Microsoft provides the Inbox Repair Tool for correcting most
problems with damaged Personal Folders .pst files. If you do not see
the Inbox Repair Tool on the Start menu, under Programs |
Accessories | System Tools, use Start | Find or Start |
Search (depending on your operating system)to search
your system for Scanpst.exe.
You will need to know the location of the .pst file that you want
to repair. See Outlook &
Exchange/Windows Messaging Backup and Dual-Boot for information
on file locations and ways to determine the location of a .pst file
that you can see in Outlook.
When you run Scanpst.exe, it performs a number of tests. If it
finds errors, it asks whether you want to make a backup copy of the
original file (always say Yes), then tries to correct the
errors.
For seriously corrupted PST files, try running Scandisk.exe (look
under Programs | Accessories | System Tools) first, then
Scanpst.exe, repeating 3-4 times until neither program returns an
error. We've know this technique to restore data that the user
though was lost forever.
If the file is on an NTFS volume, you can't use Scandisk.exe so
easily. One approach, for Windows 2000, is to open the drive in My
Computer and use the Tools menu commands to scan the disk. You may
need to restart Windows for the scan to run.
Notes
You can use Scanpst.exe not only on PST files, but also on offline
folder .ost files used for offline access to Exchange Server
folders. If an OST file is corrupted beyond the ability of
Scanpst.exe to repair it, you will need to change the settings for
the Exchange Server service (Tools | Services) to use a new
OST file, then synchronize it with the server.
Another approach is to use a
hex editor remove a single byte from the middle of the PST file,
then run Scanpst. A hex editor is a tool for editing raw files;
every Windows shareware site has several to choose from. Eugene
McCarthy of FAO Headquarters in Rome recommends the free
iHex editor, which
loads only 64kb of the file at a time, making it ideal for tinkering
with extremely large PST files. For simple Scanpst repairs, Eugene
recommends changing the first byte of the PST file from hex 21 to
00.
There is no comparable program for cleaning up corrupted Personal
Address Book (.pab) files. You may be able to view and recover PAB
data by opening the file with a hex editor.
