If you have not been watching, the Office 365 administration experience has been getting overhauls and new capabilities in the Fall of 2016. Tons of new capability and reporting is bring provided. Much of this has been based on years of feedback that have been coming from customers.
Here is the new home page that has been re-designed based on the most common tasks that are required. There is also the ability to customize the homepage based on personal preference to the activities the administrator does the most.
New activity reporting is available to give you insight into how the Office 365 service is being used.
Plus the old service health dashboard has been redesigned.
