Hello!
We've been using Google Groups for Business on our Apps for Education domain as our mailing groups, but recently discovered that forum topics (i.e. emails sent to any group) can be searched and viewed by anyone in the domain. I turned off Google Groups for Business, but that broke our nested mailing groups - some users were not receiving mails sent to a parent group...
I called Google help, which provided me this solution: in each group's Access Permissions settings, remove All Organization Members from View Topics.
Any idea if GAM provides a command to toggle this setting?
Any insight is greatly appreciated!
Jon
