Migrating old or archived Outlook data to a new email client is a common practice. And when it comes to the new version of Outlook, as it has an updated interface and features, it requires a clear understanding of how to import PST to New Outlook. Therefore, we have constructed a blog that will give the complete procedure for transferring PST files into the new Outlook application without causing any data loss.

Microsoft has been rolling out the New Outlook as the modern replacement for the classic Outlook. While it brings a refreshed interface and other performance improvements, many veteran users find it different in the import process of the PST file, as it is handled differently than before.

However, it is worth noting that New Outlook does not natively support PST import in the same way Outlook Classic did. Microsoft shifted the new Outlook towards a cloud-first model; therefore, the direct PST import functionality is limited or not present in your version.
