SysTools OST Viewer

Microsoft Outlook e-mails, contacts, notes and other items are normally stored on a remote server, but it is possible to export them to OST files so that they can be used offline.

SysTools OST Viewer is a straightforward application that allows you to open these files and explore their contents. It is a standalone tool, as it does not require Outlook to be installed on your computer.

It is possible to load any number of files simultaneously and then navigate through their contents. Folders and entries are displayed in an intuitive tree structure, allowing you to expand and collapse items easily.

If an OST file is highly corrupted, the application ca perform an advanced scan, to attempt to recover important information.

E-mail messages can be sorted depending on their sender, subject, recipient and size.

If a message contains any attachments, you can view them in a separate panel and preview their contents.

Given the considerable amount of information present in some OST files, it can be very helpful to have a way of separating items. SysTools OST Viewer allows you to view messages, calendar items, contacts, tasks, notes and journal entries in individual categories.

When you select one of these tabs, the folder tree is filtered, displaying only relevant items.

Visually, SysTools OST Viewer is rather disappointing. The user interface is somewhat outdated and would benefit from a more modern appearance and layout.

The program is difficult to use when it is not maximized, as certain fields and panels cannot be adequately displayed.

To conclude, SysTools OST Viewer is a simple application that allows you to open Microsoft Outlook OST files and explore their contents. Its functions are fairly straightforward and easy-to-use, but the program features an outdated interface that would benefit from being redesigned.
