I have to say, for many years I really had little good to say about Outlook. Once again, Microsoft is emerging from being a little on the bloated side, to being an innovator. Nifty, even.
As I personally operate on a Mac, I don't use the Outlook client application, and instead live in their web-based version at www.office.com.

The new "Sweep" button
Now, I have abandoned the concept of inbox zero, but that doesn't mean I don't want to declutter to try to improve focus. The sweep button is a super fast way to scrape your inbox for messages of certain type and either delete or archive them. The default setting will check for message from a certain sender, and delete. It's easy to adjust the setting on the fly.
A great example is doing a round of clean-up of application notifications. I'm involved in projects with Slack, Basecamp, Asana, Google Docs, and more. All of these apps send notifications from addresses like firstname.lastname@example.org. When the time comes that you dive into a project and catch up, you can then circle back and run a sweep in one shot to archive or delete notification email. Lovely!
Give it a try!
