About MS Outlook and PST files

MS Outlook, a component of MS Office Suite, is a development of Microsoft. Most commonly used as a Windows based application, its Mac based edition (Outlook 2011 for Mac) is also widely used. Due to its multi-functionalities, Outlook has been a favourite application ever since its inception.

It’s a useful app for both small scale organizations (used as a stand-alone application) and large scale organizations as well (used along with Exchange Server).

All the contents of Outlook are saved in PST format. PST stands for Personal Storage Table and contains all the emails, contacts, notes, calendar, tasks, to do lists and journal entries data of a user account.
