Outlook Recovery ToolBox is a software product for restoring destroyed or damaged data files of Microsoft Outlook mail client included into the Microsoft Office package. Outlook stores its data in PST files; these files contain messages, contacts, tasks, notes, appointments, and journals.

Outlook Recovery ToolBox reads the damaged PST file, identifies and restores information in the file. Outlook Recovery ToolBox saves the recovered information in a new PST file or in several files. An additional feature of the program is an ability of storing the recovered data in separate files:

- Recovered messages are stored in eml files (compatible with most mail clients, for example, Outlook Express).
- Recovered contacts are stored in vcf files (vCard files for storing contacts).
- Sticky Notes are kept in separate text files.

That means that each object from Outlook folders is saved to a separate file. When information is saved as separate files, the folder structure on the disk will be similar to the original folder structure in the original PST file. So, the program can be used for extracting messages, contacts and notes from Outlook data files. In Outlook it's impossible to export messages in eml format.
Outlook Recovery ToolBox reads data from PST files of all formats including Outlook 97.
Outlook Recovery ToolBox restores data from files protected with a password. Outlook Recovery ToolBox works with files larger than 2Gb; maximum size of original files is 4Gb.
