Use Groups in the Outlook mobile app; Outlook Groups app is retiring

Outlook needs to make it easier to access the other Groups tools.

Its not all about the Inbox.  For us Inbox is the least-useful part of the Group.  From Outlook, user needs to easily get to files (if that launched OneDrive or SharePoint fine), the notebook (if that launches OneNote then fine), the planner (if that launches Planner then fine), the SharePoint site (if that launches SharePoint then fine).

But as it stands right now, there will be no launching point to easily access the Groups tools without going out of the way to each individual workload's app.  That was the real benefit of the Groups app.
