Corrupted Personal Folders (.pst) File

If you suspect that your .pst file is corrupted, you may be able to recover the file by using the Inbox Repair Tool. To do so, follow these steps.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

1.	Click Start, point to Search, and then click Files or Folders.
2.	Type scanpst.exe in the Search for files or folders named box, and then click Search Now.
3.	In the list of found files, double-click the Scanpst.exe file.
4.	Type the name of the .pst file that you want to repair, or click Browse to locate the .pst file.
5.	Click Start.

If you receive an error message, you have the option to back up the file before you try to repair it.

The log file for the repair process has the same name as the .pst file with a .log file name extension. If you repair a file that is named Mailbox.pst, the log file is named Mailbox.log.

Unless you are using either Microsoft Exchange Server or Microsoft Mail services, Outlook 2003 requires a .pst file to store your e-mail messages, calendar, contacts, and tasks. If Outlook 2003 cannot find a .pst file, the only other folders that you can open are the file system folders, by using Outlook 2003 as a document explorer.
