Using classic Outlook for Windows in business environments
Hi @João Paulo Faria ,
Welcome to our forum.
According to your description, I think your are using New Outlook 365 for Mac, is it right? If so, what's the type of your account?
Based on my test, the rules are actually not supported for some accounts(such as Gmail) in New Outlook for Mac now, here is my test result below, which is same with yours. I have also tried to researched a lot about it and found some similar feedback there.
So for your normal use, it's suggested to turn off the new outlook and switch back temporarily, let's give "this new guy" a little more patience, and Microsoft is working hard on it to add more common features to the new version, hope the support for this feature in New Outlook for Mac would be back soon. You could also post your idea in our uservoice, which is the official platform that Microsoft collect the suggestions on Outlook, it may increase the priority for our engineers to create a possible option or feature that can be included in the future updates of the program.
If that's not your case or you still need further assistance, please feel free to post back.
