How to repair Outlook folders using the Inbox Repair Tool
This article describes how to use the Inbox Repair Tool for Microsoft Outlook 2000, 2002 or 2003. If you are using Microsoft Outlook 2007, we recommend you to use the Office Diagnostics tools, instead of the Inbox Repair Tool.
What is the point?
If Microsoft Office Outlook 2000 (or higher) can not open your mailbox folders and it is reporting that your Inbox folders or Outlook PST file may be damaged, then you should use the Inbox Repair Tool supplied by Microsoft. This tinny tool is installed by default when installing Microsoft Office 2000 or higher.
What is an Outlook PST file?
PST files or Personal Folder Files are used by Microsoft Outlook for storing
Outlook data, including mailbox files, email folders, contacts or any other
personal data related to Microsoft Outlook. Up to Microsoft Outlook 2002 (XP),
PST files are formatted according to the American National Standards Institute
(ANSI) format, which limits the file size to 2Gb. Starting with Microsoft
Outlook 2003, PST files are using the UNICODE format which has a limit that is
more than 20 GB.

folders. However, depending on the problem, Outlook may not be able to
automatically repair your PST file and so you will not be able to enter the main
Outlook window, as a result you will need to try and fix it using the external
Inbox Repair Tool.
