A PST (Personal Storage Table) is an Outlook data file that stores Outlook email content locally on a user’s device. Microsoft Outlook is a desktop-based email app that is Microsoft’s personal information manager. It helps users to manage and organize emails all at one place. 

Reasons to Import Old PST Files to New Outlook

Migrating PST Files to a New Outlook improves access and flexibility across platforms. The following points outline the key advantages of making this switch:

  • Importing old PST files to New Outlook preserves access to past emails, important contact lists, and restores tasks and notes.
  • The older versions of Outlook store all users’ data in PST files that haven’t been synced to any cloud services. Hence, importing the PST file is crucial.
  • When a system crash occurs, importing these PST file backups will ensure that no important data is lost. 
  • Importing PST files provides access to old communications, making them easily found and viewed within the new Outlook. 
  • Instead of recreating folders, calendars, and contacts manually, importing a PST automatically restores the original structure.

The migration of PST files can be done manually or by utilizing a conversion tool. Although manual migration is possible, but involves complex and technical steps. On the other hand, using an automated conversion tool makes everything faster and much simpler. Let’s explore both methods to see how they work.
