Soul of an office, Microsoft Outlook is an application which can manage all the personal information of the person using it. Member of the Microsoft Office family, a user can get hold onto this application from the Microsoft Office Suite. Microsoft Outlook primarily manages the emails of the user but it is perfectly capable of offering features such as calendaring upcoming events, managing tasks, sorting contacts, jotting down notes, logging in the journal. Last but not the least, the user can also use it as a web browser to browse on the internet.
PST FILES (PERSONAL STORAGE TABLE)
The files from the Microsoft Outlook are automatically stored in the PST format which is the short term for Personal Storage Table. These files created locally by Microsoft Outlook store all the databases available in the application such as mails, calendar, events, contacts, journals etc. Hence, this data is extremely important to the person as well as the organisation the person is working for.
