Dear Rhet Hulbert,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Based on your description, I understand that you have a query "No import/export feature for rules in the new Outlook".
I really understand your concern here. The lack of an import/export feature for rules in the new Outlook can be quite inconvenient, especially after investing time in setting them up. Unfortunately, as of now, the new Outlook does not support importing or exporting rules directly. While not ideal, manually recreating the rules in the new Outlook is a temporary solution. You can keep a list of your current rules and set them up again in the new interface.
Microsoft is actively developing the new Outlook, and user feedback is crucial. You can submit your feedback directly within the Outlook app by going to Help > Feedback. This can help prioritize the addition of this feature in future updates. You can also create an entry as a feature suggestion in feedback collection at Outlook · Community (microsoft.com) and many other users could vote for it. Many features of our current products are designed and upgraded based on customers’ feedback.
Alternately, if possible, you can switch back to the classic Outlook temporarily to use the import/export feature. Once you've exported your rules, you can keep the file for future use when the feature becomes available in the new Outlook.
Keep an eye on the Microsoft 365 Roadmap for updates on new features. Microsoft may add the import/export functionality in future releases based on user demand.
We really appreciate your patience and cooperation in this situation!
