In this digital age, Outlook is a well-known and mostly used application to manage information like email, contacts, calendars, events, tasks, attachments, and more. It stores our data in PST (Personal Storage Table) file format. The PST file is the only file format used by Microsoft Outlook. It keeps all our data stored together, including contacts, events, calendars, tasks, emails, and more. However, PST files reach their limits after some time of use and create many problems for all Outlook users, like slow Outlook performance, difficulty in management, and a high risk of data corruption or loss. To maintain efficiency, it’s crucial to split large PST files into smaller parts.

In this article, we will explore the best two manual methods to divide large PST files in Outlook 2019 and introduce a professional PST splitter tool for a seamless experience.
