This Is Microsoft Outlook’s Coolest New Feature | TIME

Groups provide a compelling way for Microsoft to highlight product line synergy -- across Azure (Groups are based on Azure Active Directory), Office 365 (e.g., OneDrive and Office Graph making Groups-shared content visible, permission-filtered, via Delve), and traditional Office apps (especially Outlook and OneNote)

"At first glance, Outlook Groups, part of Microsoft’s cloud-based Office 365 subscription service, looks like a shot across the bow of Slack, the messaging startup that’s taking workplaces by storm. That’s because like Slack, Groups lets users chat instead of email, straining an immeasurable amount of digital detritus from our already overflowing inboxes. But that’s where the comparisons between the two message services end. While Slack is basically a chat room for your business (with private messaging functionality), Groups also lets users share common calendars, OneDrive-hosted files, and OneNote notebooks."
