How to recover permanently deleted emails from an Outlook PST
Submitted by Dan White on June 12, 2006 - 11:17am fix and repairoutlookrepair
Make a copy of the PST. Do all of the following from this backup.
Open a hexeditor. HexEdit is a free hex editor if you need one.
Delete positions 7 through 13 with the spacebar. Since you're using hexadecimal numbering, this actually clears 13 characters in the following positions:
00007, 00008, 00009, 0000a, 0000b, 0000c, 0000d, 0000e, 0000f, 00010, 00011, 00012, 00013
(The editor displays the code "20" each time you clear a position with the spacebar.)
After clearing those positions in the file, save it. Your PST is now corrupted.
Run the Inbox Repair Tool, SCANPST.exe, to recover the file.
On Win2K and WinNT systems, the executable is located in
C:\Program Files\Common Files\System\Mapi\1033\NT.
You can also find it on the Office 2000 CD-ROM in
On Windows XP, the file is located in
C:\Program Files\Common Files\System\Mapi\1033.
And Windows XP Office XP/2002 SP2
C:\Program Files\Common Files\System\MSMAPI\1033
For additional information on the Inbox Repair Tool, see Microsoft Knowledge Base article 287497.
After creating a backup (which can be skipped because naturally you folllowed these instructions and made a backup and are now working from it), the Inbox Repair Tool repairs the damage and recreates the PST. Open the new PST in Outlook. The Deleted Items folder should contain all removed messages, so anything you've emptied will be restored.
You may have problems with very large PST's. Either the hexeditor will take an inordinately long amount of time because it's scanning the file or will simply hang - you will need patience to find out.
