Using New Outlook on Windows for professional communication and productivity
Dear Mamoun Al Homssey,
Thanks for reaching out to us here in Microsoft Community.
I understand you want to import .pst files in New Outlook. I am sorry this feature is not provided in New Outlook, and only available in Classic Outlook. New Outlook is not an updated version of Outlook. It's a free email software developed by Microsoft for unsubscribed Microsoft 365 users. The features and interface are similar to the Outlook web version. But there is still a big gap between it and Outlook Classic in terms of functionality. And the developers are constantly improving and enriching its content. So if you still have Outlook Classic, you can continue to use Outlook Classic to get more rich features.
Sorry for the inconvenience, let me explain that the community forum is a technical support forum, and the development team will not be following the community in real time.
If you want to share this issue with the development team, you can choose Feedback from the Help tab of the Outlook ribbon to report this problem or click this link Ideas · Community (microsoft.com)
You can stay tuned for Microsoft to be informed when this new feature is introduced in the future!
Best Wishes,
Stan - MSFT | Microsoft Community Support Specialist
