Using New Outlook on Windows for personal email, calendar, and contact management
Dear Benini Simone,
Good day! Thank you for reaching out.
Based on your description, I understand that you have a concern on where to import .pst files in the New Outlook. Did further checks on my end as well, please note that PST files are not yet supported in this outlook version. However, the team is aware of this requirement and is currently in the works. For now, if you heavily rely on this feature, you may consider toggling out of the new Outlook for Windows preview.
That and more features in this article. Things to look forward to in the new Outlook for Windows - Microsoft Community Hub
Kindly understand that many functions are not designed at present. I'd suggest creating an entry as a feature suggestion in feedback collection directly through your new outlook (Help-->Feedback). Many features of our current products are designed and upgraded based on customers’ feedback. Y
I will update here once I get any update on this feature.
Thank you for your understanding.
Best Regards,
Ashraf.
