Change Inactive Detection email notice process, so that all Teams/Group Owners are on distribution on the same notice instead of sending the notice to each owner individually.

This will reduce the confusion by the owners, who we find are frequently replying to the autogenerated email, adding one or more of the other Owners, as they try to figure out if the other Owners received the notice and who is going to make the decision.

If they were all on the email together, they would already see who else was notified, avoiding these extra emails.
