The renewal notifications prior to Office 365 Group expiration are great! When there are multiple Group owners, all the owners receive the notifications. So far, so good. Now, if one of the owners decides to renew the Group, wouldn't it be nice if the other owners would receive a message that this particular Group has been renewed by person X?

Saves time for the other owners, and, more importantly, when one or more owners believe the Group should expire, all the owners can at least have a discussion before the next expiration cycle.
