In this modern age of technology, email or electronic mail has become an essential part of an individual’s life. Besides an individual, large organizations and companies are also highly dependent on emails for communication purposes. Microsoft has designed an email client-based application, known as MS Outlook, that presents an advanced mailing platform for users along with some other useful features.  

Besides the mailing feature, i.e., sending and receiving messages, also supports calendaring, task managing, contact managing, note-taking, journaling, and web browsing. Because of having all these features, MS Outlook has become the most popular email application in a communication environment. To access them simultaneously, you can configure one or multiple email accounts in MS Outlook. MS Outlook stores your mailbox data into an Outlook database file known as PST. Now, let’s discuss why compact Outlook data files are required.
