Office 365 - Make a Group Hidden or Unhidden within Global Address List (GAL) or make Members Hidden from non-members

By default, when a Microsoft Group is created, the Group and its members are visible within Global Address List (GAL). This means that anyone (members and non-members) within UW-Madison's implementation of Office 365 will be able to search for and see the members of any Group.

Important:

What does it mean when a Group is hidden in the GAL?

All group functionality will continue to work, but the group not be visible in any searches. For users that are members of the Office 365 Group, the group will still appear in the navigation pane in Outlook clients. All other parameters of the group can still be managed by the group owner(s).

What does it mean when the members of the Group are hidden?

When a non-member of the group views the details of the group, the members of the group will not be available. Important: This parameter can only be set during the creation of the Group by Office 365 administrators. There is no need to perform this action if the Group is hidden in the GAL.
