When you start Microsoft Outlook 2000, or when you try to open a personal folders (.pst) file, you may receive the following error message, where Outlook.pst is the name of your .pst file: If you run the Inbox Repair tool (Scanpst.exe), the problem is not resolved and the Scanpst.exe tool may report that no errors were found.

This issue may occur if the index of the .pst file is damaged.

To resolve this issue, run the "2 GB Truncation" tool, run the Inbox Repair tool, and then open the repaired file.

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.
