Prerequisites
Before end users can invite groups, an admin must configure the following. The first two settings are enabled by default.- Enable group invites for the enterprise. In the Admin Console, go to Enterprise Settings > Content & Sharing > Collaborating on Content and select Allow users to invite group collaborators to items. This allows end users to invite groups from non-admin pages.

- Allow the specific group to be invited. Admins have granular control over who can invite individual groups into shared folders. To allow end users to invite a particular group, go to Users and Groups > Groups > Select the group, click Edit in the Group Details section, and make sure Company is selected under Permission Setting.
- Enable Shared Contacts for the inviting user. Go to Users and Groups > Managed Users > Select a user > Role and Access permissions section, and select the View managed users when inviting collaborators check box. This setting is enabled by default when a new user is created, but can be enabled or disabled per user.

Invite groups to a folder
You must be an owner, co-owner, or editor of the folder to invite collaborators.- Hover on the folder you want to share, click Share. You can also right-click and select Share.
- In the Invite People field, type the group name and see the auto-complete group list.
- Select the group.
- Click Send.
Note:
- Auto-complete is designed for short search queries, so the group name search is limited to 100 characters. Entering more than 100 characters returns no results in the auto-complete list. To find a longer-named group, type only the first part of the name and select the group from the suggestions.
- To change a group’s access level or remove a group after inviting it, see Managing Collaborators.
- If you transfer a group-collaborated folder outside the Enterprise, all group collaborations are removed.
