I think MyAnalytics is a great tool that provides you with an overview of how you, primary based on Your email/Outlook usage, spend your time at work. By summarizing this information MyAnalytics suggests how you can work “smarter”.

Great news for those of us who use Microsoft Teams even more than Outlook.
Up to now it has only been available to those of you who has an Enterprise E5 plan (or as an add-on to E1, and E3 plan). In a blog post from Natalie McCullough we can read that MyAnalytics is now becoming more broadly available and in addition to that it will also include analysis of the usage of Microsoft Teams, OneDrive and SharePoint.
in January 2019 the insights for Teams, OneDrive and SharePoint will begin to roll out to existing customers and for the new suites it will be rolling out the next couple month.
