Outlook PST file corruption can occur for several number of reasons. A typical instance is when you upgrade your Windows version. Others can be oversized PST file, network sharing, unexpected shutdown and other factors. When this occurs, Outlook Inbox Repair Tool and the Oversized PST Crop Tool can help, but can cause data loss also. To avail safe Microsoft Outlook Recovery, there are various third-party tools that run file-aware algorithms.

For instance, suppose you have a large PST. You notice that few or all of your emails disappear unexpectedly from the file. The emails are found missing even when you haven't deleted them. The file size appears to be same as that of unaffected PST.

Cause

The PST might be corrupted. Such behavior is usually observed with an ANSI formatted PST created with Outlook 2002 or an earlier version, though Outlook 2003 also supports ANSI files. The file size limitation of an ANSI formatted PST is 2 GB, but the file can show corruption much before it, typically between 1.6 GB to 1.8 GB.

Note: Make sure you are looking for the missing emails in correct folder. If you have sub-folders, search in them.

Solution

To overcome the issue discussed above, you need to repair the corrupted PST. It is highly recommended that you backup PST before applying any repair solution because irrecoverable damages are likely.

You can repair the PST using Outlook built-in tool, called Inbox Repair Tool (Scanpst.exe) as follows:

1-Click Start and point to Search (or Find)

2-Type Scanpst.exe in the Search for files and folders named box

3-Open the file to launch Inbox Repair Tool

4-Specify the file name and path of affected PST

5-Begin the repair process by clicking Start

6-Check if the PST is repaired. If not, restore from the last backup

When none of the backup works enough to bring all the emails back, you should use a PST Recovery tool. Designed to apply specific and powerful scanning algorithms, these Microsoft Outlook Recovery applications prove highly competent to repair a corrupted Outlook PST.
