I am trying to identify inactive Teams, I work for a reasonably sized company so we have hundreds of Teams setup. I have tried running a Usage Report but that only shows Teams that have had activity within the last 7, 28 or 90 days, if a Team has had no activity for over 90 days it does not seem to appear within the report.
So far the only way in which I have come up with identifying these inactive Teams is to compare the Usage report with the list of Teams manually which is less than ideal. Are there any alternatives that I am missing? I have read about running some kind of Powershell script but I am not that familiar with using Powershell.
