Have sweep rules that are easier to manage
First off, thank you for taking the time to provide the feedback and request improvements in Rules and Sweep Rules.
We have heard this feedback loud and clear and have been working to simplify and add functionality to Rules management in our new Preview Client. Right now the feature is enabled for Targeted Release tenants/Users.
If you want to try out this new feature you should ask your admin to configure you for this early release group. As we continue to validate the new experience we will slowly roll it out to all users over the coming months.
For more details about everything the New Client experience offers, you might want to check out this blog. https://techcommunity.microsoft.com/t5/Outlook-Blog/An-early-version-of-the-new-Outlook-on-the-web-will-be-available/ba-p/225338
