As Reddit user Odd_Raisin3205 asked: My father recently upgraded to Windows 11 and has over 15 years of Outlook email archives. All data is stored inside a PST file that is larger than 1GB. He does not use a Microsoft account or an Outlook.com email address. Outlook now says a Microsoft 365 subscription is required to access PST files. Is there a way to import PST to new Outlook without Microsoft 365 while keeping all emails intact?

In case your archives include many emails, you may choose a PST converter, as it will allow you to view everything without using Microsoft applications at all.

How to Migrate PST to New Outlook Using the Built-In Way?

Microsoft allows the import of PST files using Classic Outlook. The new Outlook experience doesn’t provide the PST import facility provided by the Classic Outlook version.

A way around this problem is to revert to Classic Outlook, perform the PST import operation, and then use Outlook to view the mailbox. But you will have to install Outlook to get the process done.

The following steps need to be performed:

  9. Further, choose where you want to save the imported data.
  10. Select the option Include Subfolders, if needed.
  11. Meanwhile, complete and allow Outlook to finish PST importing.
  12. The final step will be checking email, contacts, and folders in Outlook.

Why Is This Method Not Ideal?

  • Installation of the Classic Outlook is necessary.
  • It cannot be performed for New Outlook directly.

  • There are no advanced filtering capabilities.
  • PST files cannot be imported in bulk.
  • Debugging the process becomes quite tough.
