Google recently announced that Google Calendar invitations sent to members of a Google Group will automatically update as people join or leave the group. This feature will not be immediately available on the UMICH domain. As part of maintaining the privacy settings available in MCommunity, specific features in M+Google have been disabled. Because these features are disabled, the enhancements to Google Calendar will not work. We are working on bringing these enhancements to your M+Google account, but no timeline has been set.
