A year is a long time in Office 365. Lots changes in that time, so it's good to go back and look at some PowerShell written to report Teams and Groups activity. Improvements can be made, advantage taken of changes made by Microsoft, and generally the whole thing can be tidied up and upgraded. PowerShell makes it easy to do - and to change if you don't like what I've done.
