Small announcement but there are new reports being made
available in the Office 365 Admin center.
Consider it a re-vamping and expansion of what you already had. There are new activity dashboards that give
you a cross service visibility into how Office 365 is being used by your end
users. Reports are available for the
organization and can be taken down to the individual user view.
Here is the top level report.
Here is a drill down the email activity report.
Right now there are reports on active users,
email activity and Office ProPlus activations.
More reports are coming on SharePoint Online, OneDrive for Business
Skype for Business Online, Yammer, etc.
