Outlook Forensic Toolbox is designed to reveal hidden and deleted information from Microsoft Outlook data files (files with PST and OST extensions). The tool performs forensic analysis of Microsoft Outlook data stores, in which all objects are saved: letters, contacts, reminders, files, attachments, and more.

Outlook Forensic Toolbox retrieves deleted and hidden data that is not exposed under normal viewing of PST / OST files in Microsoft Outlook.

An array of hidden information:

  1. whole letters
  2. contacts
  3. attached files
  4. meetings
  5. reminders
  6. tasks
  7. notes
  8. calendar
  9. magazines
outlook forensics

Or partly restored objects or service information from objects as well:

  • service headers of letters
  • text fragments
  • parts of files
  • parts, fragments, or blocks of letters
  • nested objects

The principle of the program is to search for blocks with data that are not provided in Microsoft Outlook. Such hidden blocks with user data can appear when running Microsoft Outlook when optimizing data storage or after user data.

For example, the user received an unwanted email or the content of the message is confidential and must be removed. In this scenario, the Microsoft Outlook user presses the Delete button, and the email stops in the mail program. When the Delete button is destroyed, Outlook deletes the letter / contact / journal or other objects from the object list. But blocks with deleted message data remain in Microsoft Outlook storage (in PST / OST files). Outlook Forensic Toolbox finds such data blocks, analyzes their content, and, using complex forensic analysis algorithms, recreates the object in whole or in part.

Requirements:

  • Windows 98/Me/2000/XP/Vista/7/8/10/11 or Windows Server 2003/2008/2012/2016 and above
Note:

In some cases, it is not possible to completely recreate the object, since all 100% of the blocks with information about the object are not always enough for any reason (overwritten in the file with other data, the link to the nested object is lost, etc.). In case of incomplete recovery of a deleted object, separate files are saved with what was identified and reconstructed.

FAQ-Wiki:

Question:

When recovering deleted objects from a PST file using Outlook Forensic Toolbox, some emails end up lacking some of their content. That is, emails have From, To, and Subject fields, but no email body and/or attachments

Answer:

Every object saved by Outlook to a file is stored in several blocks of up to 512 bytes. When a message is deleted, these blocks are not deleted and remain in the file. However, when new emails are sent or received, these blocks may be overwritten. As a result, the deleted email can be recovered only partially, for example:

  1. if there is a subject, the message body or attachments may be lost;
  2. if the subject is lost but the body is there, the email will be restored without From and To fields;
  3. if the message subject and body have been overwritten, the attachment will be saved as a standalone file;
  4. and so forth.

Outlook Forensic Toolbox does everything possible to recover deleted data. If an object's data blocks are overwritten by Outlook, the object will be recovered only partially.
