Microsoft Outlook can save your email messages, contacts, notes, tasks and other such items to OST or PST files, and it is often necessary to convert data between these two formats.

ZOOK OST to PST Converter is a relatively simple utility that enables you to migrate your Outlook data in a few easy steps. It can convert numerous files at once, and it is very intuitive, but it lacks a few useful features.

This application is primarily aimed at users who often need to process large numbers of files, as it can reduce the required effort considerably, in addition to saving you a great deal of time. It can convert any number of OST files in one operation, and it requires minimal user input.

When importing the source OST files, you can simply select their containing directory to have the program load them all in one go, but it is also possible to add them individually. Sadly, though, drag and drop actions are not supported.

Unfortunately, there is no way to view a complete list of the files that have been added to the conversion queue. Because of this, you cannot remove certain items after importing every file from a large directory.

ZOOK OST to PST Converter maintains the original formatting of the migrated emails, and attachments are also transferred automatically. However, because the application does not allow you to view the contents of each file, it is not possible to extract specific items or folders.

All in all, ZOOK OST to PST Converter is a simple and reliable program that can help you transfer your Outlook emails, notes, tasks and contacts from OST to PST files. It features a minimalistic user interface and is very novice-friendly, but it does lack a few important features.
