I started to use filters on my incoming email in ms outlook (office 2019 pro) to split it into different (sub)folders. But now the outlook envelope icon no longer shows in the taskbar when a new email arrives. The incoming email is split based on the "to" address. It 's an email account with several aliases, which are delivered to the same inbox on the server. Is there a way to keep the envelope icon in the taskbar and still split the new email into different (sub)folders?

Create a smart folder

Thanks for the input, but I think smart folders are only available in the MAC version.
