PST Ghostbuster is a free program for Microsoft Windows that enables you to remove duplicate PST files from Microsoft Outlook 2010 or earlier.

It can happen that duplicate pst files appear in Microsoft Outlook. These files are sometimes referred to as ghost files which are displayed in the folder list and other folder views in the email client. These duplicate pst files can be very problematic as they cannot be deleted easily from Outlook usually.

While you could ignore them, having the same menu or folder structure twice in Outlook can be confusing and may also decrease manageability of mail folders.

Error messages such as "Object was not found", "The operation failed. An object could not be found" or " Can't open this item. The object could not be found" are often displayed when the user tries to remove them from Outlook.

That leaves the Outlook user with no other option than to create a new Outlook profile which means that all settings, accounts and other information and personal preferences will not be carried over.

CodeTwo PST Ghostbuster is a portable program that resolve issues with duplicate pst files in Microsoft Outlook.

The program can be used to automatically remove duplicate pst files from a Microsoft Outlook profile with little user input required.

It displays a menu and a text form in its interface on start which you use to initiate the process.The menu is used to select the Outlook profile which experiences the ghosting issues, the form to enter the display name of the folder that appears several times in the desktop email client.

A click on the check button scans the Outlook profile for duplicate pst files. A duplicate entry was found and can be cleaned if the message "Invalid sections that should be removed were found" is displayed to the user. Clicking on the repair button will then resolve the issue so that the duplicate pst file is removed from Microsoft Outlook.

PST Ghostbuster can be downloaded from the developer's website. It is compatible with Microsoft Outlook 98 to Outlook 2010, and Windows 2000 to Windows 10.
