Dear Tony
I am starting to appreciate that these easy to use buttons apps (inside the office ribbon) are sometimes a better way to "fill in" the features in Office 365 and Azure.
Groups is an interesting object. You can provide certain capabilities to "Owners" of the Group that don't require an IT or Powershell type of solution. In many cases the Group Owner or Member can be an Outlook user who doesn't have or need Powershell. Eventually Microsoft will catch up the UI elements in Groups as they have been doing in Office 365. For now, we can fill in with addins to the UI for some of those missing elements.
We create many custom addins for customers making the move to Office 365 and Azure and each one seems to make the transition easier, faster and better. Change is always hard and ease of use or the familiarity of the Office apps can increase adoption and in some cases, remove the barrier for making the move.
MS Graph give us a standard way to create or update most objects throughout all the services making it efficient and affordable to do the apps for customers even in a simple example like this one. The value can be in the Outlook user maintaining the setting rather than an IT request.
