Teams End Date
In order to keep the number of inactive/old/no longer used "teams" from exploding, have a way to set an "end date" for the Team. I wouldn't want to have the end date for the O365 Group (that the Team is based on), since that group may be used for other applications.
Maybe x number of days prior to end date, an email is sent to the Team owner, and then repeat the email for x number of days after the end date.
After a certain number of emails, disable the Team. After a month(s), delete the Team.
