Conveniently, Microsoft Outlook stores all of your information, such as Contacts, Calendar, Notes, and, of course, mail, in one PST file, and IMAP accounts are stored in separate OST files. However, if this file is damaged due to a power outage, system error recording, virus attack or otherwise, Outlook will not be able to open it. In this case, only special programs such as Recovery Toolbox for Outlook (https://outlook.recoverytoolbox.com/), can help, since they can repair corrupted content of Outlook data files and can also be used as a format converter. Let us take a good look at this tool.

1. File client for Microsoft Outlook
Microsoft Outlook typically uses a PST file as a data store. A PST file is often called a “Personal Store Folder” or simply an Outlook data file. Outlook uses a PST file as a container and stores all of the Outlook Personal Manager information in it, such as contacts, appointments, notes, tasks and, of course, all emails that the user sends and receives.
If Outlook uses a connection to the Exchange Server or exchanges emails using the IMAP protocol, Outlook utilizes additional offline Outlook data files (OST) to store information separately for each account. Prior to Outlook 2013, PST files were also used for IMAP accounts.
An OST file is basically just a synchronized copy of the mailbox (Exchange Server or IMAP), therefore the loss is less dramatic. If necessary, you simply need to re-create the account and synchronize again. However, this will be problematic if synchronization is not possible, or if there are authorization failures on the server (the account is locked or Windows Domain Controller is not working). In this case, restoring the OST file is a necessary option.
OST files have one important limitation: their contents cannot be easily imported into the system. If you want to import the contents of an OST file into Outlook, this is only possible after conversion using specialized programs, such as Recovery Toolbox for Outlook.
By default, Microsoft Outlook saves your PST and OST files in
C:Documents and SettingsUSERNAME Local SettingsApplication Data MicrosoftOutlook ???
You can also independently change the folder for storing files.
Please note: In Outlook 2013, a different path to the storage is used by default: “DocumentsOutlook Files”.
2. Possible causes of corrupted PST files
Outlook data files may be corrupted in various ways. The most common causes are:
- erroneous entries due to power failure
- virus attacks
- program errors
- Windows or Outlook crashes with an open PST file
- network connection failure if the file is in the network storage
- defects in network data storage
- incorrect operation of the ScanPST program
Users of MS Outlook 97-2002 must have 2 GB for the PST Outlook data file. If this size is exceeded, the data file can no longer be processed.

Recovery Toolbox for Outlook can also recover PST files larger than 2 GB. However, it should be noted that we recommend recovering large files on computers with the 64-bit version of Microsoft Outlook installed due to Windows limitations.
For users of Microsoft Office 365, it is recommended to use the online version of the program here https://outlook.recoverytoolbox.com/online/ to bypass the requirement to install the full version of Microsoft Outlook.
b. ScanPST or special programs instead?
Microsoft provides a PST file scanner (SCANPST.exe) as free software to recover corrupted Outlook data files (PST and OST). SCANPST.exe is called from and is located in the subfolder C: Program Files (x86)Microsoft Office or it can be downloaded as MicrosoftFixit20101.mini.diagcab for Outlook 2013 or 2016, as well as MicrosoftFixit50569.msi for Outlook up until version 2010.
Scanpst searches for errors in the PST file and attempts to fix them, but usually can only help with files that were not seriously damaged. “Inbox Repair Tool” (ScanPST.exe) offers its users the possibility to back up the PST file before making any changes. So as not to damage them for other recovery tools – such as Recovery Toolbox for Outlook – make sure to back up and continue.
If ScanPST cannot solve the problem or if you wish to recover deleted mail in the PST file, you will need special software. By the way, such data recovery tools as Recuva usually will not work, because the file structure on the disk remains unchanged and is not removed, and the structure of data in the PST file is damaged.
c. Repair Outlook data file
After installation, first select the corresponding Outlook data file that is corrupted or that contains the items that you want to repair.
Recovery Toolbox for Outlook, selecting a PST or OST file
In the next step, you will select the operating mode of the program:
- Recovery is used to recover damaged PST or OST files.
- Conversion mode can convert undamaged OST files into one PST file, import contents of an OST file into Outlook at a later time or extract contents of PST/OST files in different formats, such as MSG / EML or VCF.
- Deleted file search function attempts to find content marked as deleted in the Outlook file.
In the recovery mode, the program analyzes the file, which can take a long time depending on the size of the source file.
Analyzing data with Recovery Toolbox for Outlook
When the analysis is completed, Recovery Toolbox for Outlook displays the found items.
Items found in the data file
In the next step, you have the opportunity to create a new PST file or save all the content separately.
Storage type selection
If you choose the second option – “Save data separately” – you can specify the file format for emails, contacts and notes. You will be able to select MSG, EML, VCF, or TXT format. Calendar, log and tasks are always saved in the MSG format.
Save the files separately
In the “Search deleted objects” mode, the contents of the PST file are also analyzed, but in this case only deleted objects are displayed if they are still available and not yet overwritten. The process of recovering deleted emails, contacts, files and other objects that were found is identical to the PST file recovery process.
- The utility that is very easy to use
- Ability to convert OST files into PST files
- Ability to extract individual items or folders, for example, only Contacts
- Trial version cannot recover more than 5 objects per folder
