Scanpst is an inbuilt utility which gets installed as soon as the user installs the Outlook email client on their system. The main purpose of this inbuilt utility is to diagnose and repair damaged and corrupt Personal folders (.pst) and Offline Data (.ost) files.
The Inbox Repair tool is useful when the OST or PST file is damaged or corrupt. However, Inbox Repair can only be used to scan only PST and OST files and not the mailbox on Server.
Inbox Repair works by scanning the complete PST or OST to determine whether the file structure is intact or not. In case any issue arises with the file structure, it first reassembles the structure and then rebuilds the header of your original PST or OST file. Sometimes the file is not recovered in a single go; you may have to perform several iterations of the repair process to recover the file. The number of iterations depends on the intensity of corruption.
Now, before using this free inbuilt utility, you should first know how to locate the tool on your Windows system. The exact location of the tool can vary depending on the versions of Office Suite as well as the installation type. Also, it depends on the version of Windows you are currently using (32 or 64 bit).
