One-sheet on Office 365

Hi Steven. Producing a one-sheet quick reference for end users is becoming more and more difficult with Office 365. When it comes to Office 365 Groups, it represents a collection of communication, collaboration and coordination tools. Thinking of communication tools alone, you'd need something that represents Outlook Groups, Yammer and Microsoft Teams. For Files, you'd need something that covers basic file activities across SharePoint and OneDrive. Covering Shared Calendar, OneNote, Planner, PowerBI... and each of these can change UI. It's difficult to keep up with change. 

I put this question to others following the Office 365 Groups Community - What would you put in a basic guide for Groups? Let's start with Outlook Groups as the choice of communication.

Subscribing to Group activity - Inbox and Events

• Creating a new message from Outlook Web Access - from within the Group and from your own Inbox.
• Creating new message from Outlook 2016 - from within the Group and from your own Inbox.
